• CD47 prevents the elimination of diseased fibroblasts in scleroderma. JCI insight Lerbs, T., Cui, L., King, M. E., Chai, T., Muscat, C., Chung, L., Brown, R., Rieger, K., Shibata, T., Wernig, G. 2020; 5 (16)

  Abstract

  Scleroderma is a devastating fibrotic autoimmune disease. Current treatments are partly effective in preventing disease progression but do not remove fibrotic tissue. Here, we evaluated whether scleroderma fibroblasts take advantage of the "don't-eat-me-signal" CD47 and whether blocking CD47 enables the body's immune system to get rid of diseased fibroblasts. To test this approach, we used a Jun-inducible scleroderma model. We first demonstrated in patient samples that scleroderma upregulated transcription factor JUN and increased promoter accessibilities of both JUN and CD47. Next, we established our scleroderma model, demonstrating that Jun mediated skin fibrosis through the hedgehog-dependent expansion of CD26+Sca1- fibroblasts in mice. In a niche-independent adaptive transfer model, JUN steered graft survival and conferred increased self-renewal to fibroblasts. In vivo, JUN enhanced the expression of CD47, and inhibiting CD47 eliminated an ectopic fibroblast graft and increased in vitro phagocytosis. In the syngeneic mouse, depleting macrophages ameliorated skin fibrosis. Therapeutically, combined CD47 and IL-6 blockade reversed skin fibrosis in mice and led to the rapid elimination of ectopically transplanted scleroderma cells. Altogether, our study demonstrates the efficiency of combining different immunotherapies in treating scleroderma and provides a rationale for combining CD47 and IL-6 inhibition in clinical trials.

• PRAME expression in melanocytic proliferations with intermediate histopathologic or spitzoid features. Journal of cutaneous pathology Raghavan, S. S., Wang, J. Y., Kwok, S., Rieger, K. E., Novoa, R. A., Brown, R. A. 2020

  Abstract

  BACKGROUND: PRAME (PReferentially expressed Antigen in MElanoma) has shown utility in distinguishing melanoma from benign melanocytic lesions, but knowledge of its expression pattern in intermediate melanocytic and spitzoid proliferations is limited.METHODS: Immunohistochemical expression of PRAME was examined in 112 melanocytic proliferations with intermediate histopathologic or spitzoid features.RESULTS: Any intensity of PRAME staining in at least 60% of lesional melanocytes was determined as the best threshold for diffuse staining in this cohort. Nearly all non-spitzoid melanomas (23/24; 95.8%) demonstrated diffuse PRAME expression. PRAME was completely negative in 95.6% (43/45) of mitotically-active nevi, traumatized nevi, nevi with persistent/recurrent features, and dysplastic nevi. Most Spitz nevi (15/20) and atypical Spitz tumors (10/13) entirely lacked PRAME expression. One Spitz nevus, one atypical Spitz tumor, and one case of spitzoid melanoma (1/2) demonstrated diffuse PRAME expression.CONCLUSIONS: Although diffuse PRAME expression is generally limited to malignant melanoma, benign Spitz nevi and atypical Spitz tumors can infrequently express diffuse PRAME. PRAME immunohistochemistry can be useful in the evaluation of atypical melanocytic proliferations with intermediate histopathologic features but should be interpreted with caution in the setting of spitzoid neoplasms.

• Diagnostic Utility of LEF1 Immunohistochemistry in Differentiating Deep Penetrating Nevi From Histologic Mimics. The American journal of surgical pathology Raghavan, S. S., Saleem, A., Wang, J. Y., Rieger, K. E., Brown, R. A., Novoa, R. A. 2020

  Abstract

  Deep penetrating nevi (DPNs) are intermediate grade lesions which have the capacity to recur, metastasize, or progress to melanoma. Differentiating DPN from other melanocytic lesions including blue and cellular blue nevi can be diagnostically challenging, and markers to distinguish these entities can be useful. Mutations of the beta-catenin and mitogen-activated protein kinase pathways have recently been elucidated as distinctive of DPN. This pathway can subsequently activate lymphoid enhancer-binding factor 1 (LEF1), a transcription factor shown to facilitate the epithelial-mesenchymal transition to propagate tumorigenesis. Seventy-two cases in total were examined on hematoxylin and eosin sections and with beta-catenin and LEF1 immunohistochemistry. This included: DPN (14), cellular blue nevi (19), blue nevi (15), congenital melanocytic nevi (12), and melanoma (12). Nuclear expression of LEF1, present throughout the entire depth of the lesion, was noted in 13/14 (93%) of DPN, 0/19 (0%) of cellular blue nevi, 0/15 (0%) of blue nevi, 1/12 (8%) of congenital melanocytic nevi, and 9/12 (75%) of melanoma cases. Nuclear expression of beta-catenin, present throughout the entire depth of the lesion, was noted in 14/14 (100%) of DPN, 0/18 (0%) of cellular blue nevi, 0/15 (0%) of blue nevi, 1/12 (8%) of congenital melanocytic nevi, and 1/12 (8%) of melanoma cases. A majority of congenital melanocytic nevi demonstrated a gradient of LEF1 and beta-catenin expression with more intense staining superficially and loss of staining with increasing depth. Deep, uniform nuclear LEF1 combined with beta-catenin immunohistochemical staining can be useful in distinguishing DPN from histologic mimics.

• Histopathologic Characterization of Mogamulizumab-associated Rash. The American journal of surgical pathology Wang, J. Y., Hirotsu, K. E., Neal, T. M., Raghavan, S. S., Kwong, B. Y., Khodadoust, M. S., Brown, R. A., Novoa, R. A., Kim, Y. H., Rieger, K. E. 2020

  Abstract

  Rash is one of the most common adverse events observed with mogamulizumab, an anti-C-C chemokine receptor 4 monoclonal antibody approved for previously treated mycosis fungoides (MF) and Sezary syndrome (SS). Given the nonspecific clinical presentations of this rash, histopathologic distinction from MF/SS is critical for informing clinical management. We performed a comprehensive characterization of the histopathologic findings in mogamulizumab-associated rash (MAR) with the integration of high-throughput sequencing of T-cell receptor (TCR) genes. Fifty-two biopsy specimens from 19 patients were evaluated retrospectively. Three major histologic reaction patterns were identified: spongiotic/psoriasiform dermatitis (33/52), interface dermatitis (11/52), and granulomatous dermatitis (8/52). Almost half of the specimens (21/52) showed at least 2 of these reaction patterns concurrently. Dermal eosinophils were not a consistent feature, being present in only half (27/52) of specimens and prominent in only 3. Features mimicking MF/SS, including lymphocyte exocytosis, lamellar fibroplasia, and adnexal involvement, were commonly seen but tended to be focal and mild. In 38/43 specimens with available immunohistochemistry, intraepidermal lymphocytes demonstrated a CD4:CD8 ratio ≤1 : 1. Low background levels of the patient's previously identified MF/SS-associated TCR sequence(s) were demonstrated in 20/46 specimens analyzed by high-throughput sequencing of TCR. We conclude that MAR may demonstrate diverse histologic features. Findings that may distinguish MAR from MF/SS include the inverted or normalized CD4:CD8 ratio within intraepidermal lymphocytes and demonstration of absent or nondominant levels of disease-associated TCR sequences. Correlation with the clinical findings and immunohistochemical and molecular characterization of the patient's MF/SS before mogamulizumab, when possible, may facilitate recognition of MAR.

• Phase 1/2a clinical trial of gene-corrected autologous cell therapy for recessive dystrophic epidermolysis bullosa. JCI insight Eichstadt, S., Barriga, M., Ponakala, A., Teng, C., Nguyen, N. T., Siprashvili, Z., Nazaroff, J., Gorell, E. S., Chiou, A. S., Taylor, L., Khuu, P., Keene, D. R., Rieger, K., Khosla, R. K., Furukawa, L. K., Lorenz, H. P., Marinkovich, M. P., Tang, J. Y. 2019; 4 (19)

  Abstract

  BACKGROUNDRecessive dystrophic epidermolysis bullosa (RDEB) patients have mutations in the COL7A1 gene and thus lack functional type VII collagen (C7) protein; they have marked skin fragility and blistering. This single-center phase 1/2a open-label study evaluated the long-term efficacy, safety, and patient-reported outcomes in RDEB patients treated with gene-corrected autologous cell therapy.METHODSAutologous keratinocytes were isolated from participant skin biopsies. Epidermal sheets were prepared from cells transduced with a retrovirus carrying the full-length human COL7A1 gene. These gene-corrected autologous epidermal sheets measured 5 * 7 cm (35 cm2) and were transplanted onto 6 wound sites in each of 7 adult participants (n = 42 sites total) from 2013 to 2017. Participants were followed for 2 to 5 years.RESULTSNo participants experienced any serious related adverse events. Wound healing of 50% or greater by Investigator Global Assessment was present in 95% (36 of 38) of treated wounds versus 0% (0 of 6) of untreated control wounds at 6 months (P < 0.0001). At year 1, 68% (26 of 38) of treated wounds had 50% or greater healing compared with 17% (1 of 6) of control wounds (P = 0.025). At year 2, 71% (27 of 38) of treated wounds had 50% or greater healing compared with 17% (1 of 6) of control wounds (P = 0.019).CONCLUSIONC7 expression persisted up to 2 years after treatment in 2 participants. Treated wounds with 50% or greater healing demonstrated improvement in patient-reported pain, itch, and wound durability. This study provides additional data to support the clinically meaningful benefit of treating chronic RDEB wounds with ex vivo, C7 gene-corrected autologous cell therapy. This approach was safe and promoted wound healing that was associated with improved patient-reported outcomes.TRIAL REGISTRATIONClinicaltrials.gov identifier: NCT01263379.FUNDINGEpidermolysis Bullosa Research Partnership, Epidermolysis Bullosa Medical Research Foundation, NIH R01 AR055914, Office of Research and Development at the Palo Alto Veteran's Affairs Medical Center, and the Dermatology Foundation.

• Intralymphatic Rosai-Dorfman Disease Associated With Vulvar Lymphedema: A Case Report of an Extremely Rare Phenomenon. International journal of gynecological pathology : official journal of the International Society of Gynecological Pathologists Saleem, A., Hoffmann, J., Warnke, R., Rieger, K. E., Longacre, T. 2019

  Abstract

  Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman disease (RDD), is a self-limited histiocytic disorder of unclear etiology which most commonly presents with cervical lymphadenopathy. Purely extranodal presentation of RDD is uncommon, and isolated intralymphatic/intravascular confinement of this entity has not previously been described. We report a 16-yr-old female who presented with vaginal swelling and mass-like enlargement of the right labia. The mass had been present for nearly a year without pain or tenderness. Clinically, the lesion was thought to be a Bartholin gland cyst. Following surgical resection, histologic examination demonstrated a hypocellular myxedematous stroma with a mixture of ectatic thin and thick-walled vessels within which there were numerous collections of histiocytes, lymphocytes, and plasma cells. The histopathologic differential diagnosis included localized vulvar lymphedema, a specialized genital tract neoplasm, and childhood asymmetric labium majus enlargement. The histiocytes showed occasional plasma cells and lymphocytes within their cytoplasm, consistent with emperipolesis. Immunohistochemical studies showed that the histiocytes expressed CD163 and S100, while ERG and D2-40 highlighted their intralymphatic confinement, ultimately leading to the diagnosis of intralymphatic RDD. Intralymphatic RDD may present as vulvar lymphedema and can potentially mimic other myxedematous neoplasms of the vulvovaginal region.

• Clinical factors associated with cutaneous histopathologic findings in dermatomyositis. Journal of cutaneous pathology Wolstencroft, P. W., Rieger, K. E., Leatham, H. W., Fiorentino, D. F. 2019

  Abstract

  BACKGROUND: Common histopathologic findings in cutaneous dermatomyositis include vacuolar interface with dyskeratosis, mucin, and perivascular inflammation. Data examining the relationships between these and other histologic abnormalities, or their dependence on biopsy site, and medications are limited.METHODS: Using 228 dermatomyositis skin biopsies and statistical analyses including Chi-squared analyses, calculations of relative risk, and adjusted generalized estimating equation regressions, we investigated relationships between 14 histopathologic findings and the impact of clinical factors on these findings.RESULTS: In biopsies taken from sites of visible rash, interface dermatitis was seen in 91%, and 95% had at least one of perivascular inflammation, mucin, or basal vacuolization. Vascular abnormalities were not closely associated with epidermal or inflammatory findings. Concomitant prednisone significantly decreased the odds of basal vacuolization (odds ratio [OR]=0.34, 95% confidence interval [CI]: 0.12-0.98, P-value=0.05), perivascular inflammation (OR=0.19, 95% CI: 0.07-0.53, P-value=0.002), and vessel damage (OR=0.81, 95% CI: 0.68-0.96, P-value=0.02).CONCLUSION: Vasculopathy and classic findings of interface dermatitis may be driven by unique pathways in dermatomyositis. Corticosteroid use may impact skin biopsy findings. There is a need for clinicopathologic correlation when diagnosing dermatomyositis.

• Loss of primary cilia drives switching from Hedgehog to Ras/MAPK pathway in resistant basal cell carcinoma. The Journal of investigative dermatology Kuonen, F., Huskey, N. E., Shankar, G., Jaju, P., Whitson, R. J., Rieger, K. E., Atwood, S. X., Sarin, K. Y., Oro, A. E. 2019

  Abstract

  Basal cell carcinomas (BCCs) rely on Hedgehog (HH) pathway growth signal amplification by the microtubule-based organelle, the primary cilium. Despite naive tumors responsiveness to Smoothened inhibitors (Smoi), resistance in advanced tumors remains frequent. While the resistant BCCs usually maintain HH pathway activation, squamous cell carcinomas with Ras/MAPK pathway activation also arise, with the molecular basis of tumor type and pathway selection still obscure. Here we identify the primary cilium as a critical determinant controlling tumor pathway switching. Strikingly, Smoi-resistant BCCs possess an increased mutational load in ciliome genes, resulting in reduced primary cilia and HH pathway activation compared to naive or Gorlin patient BCCs. Gene set enrichment analysis of resistant BCCs with a low HH pathway signature reveals increased Ras/MAPK pathway activation. Tissue analysis confirms an inverse relationship between primary cilia presence and Ras/MAPK activation, and primary cilia removal in BCCs potentiates Ras/MAPK pathway activation. Moreover, activating Ras in HH-responsive cell lines confers resistance to both canonical (vismodegib) and non-canonical (aPKC and MRTF inhibitors) HH pathway inhibitors, while conferring sensitivity to MAPK inhibitors. Our results provide insights into BCC treatment and identify the primary cilium as an important lineage gatekeeper, preventing HH to Ras/MAPK pathway switching.

  Abstract

  Protein biomarkers for diagnosis and prognosis are currently lacking for melanoma, which predominantly relies on histologic features for diagnosis (cytologic and nuclear pleomorphism, growth pattern) and staging (Breslow depth, ulceration). In many cases, the histology of the primary tumor is an unreliable predictor of tumor behavior, and consequently sentinel lymph node biopsy along with imaging studies are often necessary to predict likelihood of mortality from disease.

  Abstract

  A term, appropriate-for-gestational-age, male infant born via normal spontaneous vaginal delivery presented at birth with a full-body erythematous, vesiculobullous rash. He was well-appearing with normal vital signs and hypoglycemia that quickly resolved. His father had a history of herpes labialis. His mother had an episode of herpes zoster during pregnancy and a prolonged rupture of membranes that was adequately treated. The patient underwent a sepsis workup, including 2 attempted but unsuccessful lumbar punctures, and was started on broad-spectrum antibiotics and acyclovir, given concerns about bacterial or viral infection. The rash evolved over the course of several days. Subsequent workup, with particular attention to his history and presentation, led to his diagnosis.

  Abstract

  To our knowledge, there have been no previous reports of eruptive keratoacanthomas (KAs) in patients receiving pembrolizumab.To report the cases of 3 consecutive patients with pembrolizumab-induced eruptive KAs and their management.Case report study of 3 patients from 2 centers with pembrolizumab-treated cancer who all developed eruptive KAs.All 3 patients had AK treatment with clobetasol ointment and intralesional triamcinolone; 2 patients also underwent open superficial cryosurgery.Three consecutive patients with cancer, 2 men and 1 woman (median age, 83 years; range 77-91 years), experienced pembrolizumab-associated eruptive KAs. All patients presented with a sudden onset of multiple lesions on sun-exposed areas of their extremities after a median of 13 months (range, 4-18 months) of pembrolizumab therapy. On lesional biopsy, a lichenoid infiltrate was observed in the underlying dermis, predominantly composed of CD3+ T cells, scattered CD20+ B cells, and relatively few PD-1+ (programmed cell death 1-positive) T cells, an immunophenotypic pattern also observed in other cases of anti-PD-1-induced lichenoid dermatitis. Patients were treated with clobetasol ointment and intralesional triamcinolone, alone or in combination with open superficial cryosurgery. All KAs resolved in all patients, and no new lesions occurred during close follow-up. Pembrolizumab treatment was continued without disruption in all 3 cases, and all patients had complete responses of their primary cancers.Pembrolizumab is used in advanced melanoma, advanced non-small-cell lung cancer, and in head and neck cancer. A variety of dermatologic immune-related adverse events including maculopapular eruption, lichenoid reactions, pruritus, and vitiligo have been described. This case series demonstrates that pembrolizumab therapy may also be associated with eruptive KAs with characteristic dermal inflammation, which improved with corticosteroid treatment (topical and intralesional) alone or in combination with cryosurgery, allowing patients to continue therapy with pembrolizumab.

• Intraepidermal Type VII Collagen by Immunofluorescence Mapping: A Specific Finding for Bullous Dermolysis of the Newborn. Pediatric dermatology Heinecke, G., Marinkovich, M. P., Rieger, K. E. 2017; 34 (3): 308-314

  Abstract

  Bullous dermolysis of the newborn (BDN) is a subtype of dystrophic epidermolysis bullosa (DEB) characterized by skin fragility and blister formation at birth that typically resolves within the first year of life. Abnormal intraepidermal retention of type VII collagen (C7) has been reported as a characteristic feature of BDN, but few studies have investigated the specificity of this finding.We retrospectively reviewed pathology reports of patients diagnosed with DEB using immunofluorescence mapping from January 2001 to January 2015. For cases describing intraepidermal accumulation of C7, we collected information on patient characteristics, including genetic testing results, clinical outcome, and concurrent electron microscopy findings, where available.Of the 143 cases of DEB with immunofluorescence mapping, eight patients had intracytoplasmic epidermal retention of C7. Of these eight patients, two were lost to follow-up, four had complete resolution of bullae, and two had marked improvement with rare residual bullae. Concurrent electron microscopic findings available for three patients were consistent with BDN.Our review of immunofluorescence mapping findings in patients with DEB found that 5.6% had abnormal intracytoplasmic epidermal retention of C7, a finding previously reported in BDN. All such patients with clinical outcomes available had resolution or marked improvement of bullae, consistent with clinical outcomes expected in BDN.

  Abstract

  Classic mycosis fungoides (MF) presents with patches and plaques on the trunk and proximal extremities. However, numerous clinicopathologic variants have been described, making diagnosis challenging. Here, the authors report a 21-year-old woman with immunophenotypically and molecularly confirmed MF occurring in a dermatomal distribution. Awareness of this and other rare variants of MF is critical to avoid misdiagnosis.

• Safety and Wound Outcomes Following Genetically Corrected Autologous Epidermal Grafts in Patients With Recessive Dystrophic Epidermolysis Bullosa. JAMA Siprashvili, Z., Nguyen, N. T., Gorell, E. S., Loutit, K., Khuu, P., Furukawa, L. K., Lorenz, H. P., Leung, T. H., Keene, D. R., Rieger, K. E., Khavari, P., Lane, A. T., Tang, J. Y., Marinkovich, M. P. 2016; 316 (17): 1808-1817

  Abstract

  Recessive dystrophic epidermolysis bullosa (RDEB) is a devastating, often fatal, inherited blistering disorder caused by mutations in the COL7A1 gene encoding type VII collagen. Support and palliation are the only current therapies.To evaluate the safety and wound outcomes following genetically corrected autologous epidermal grafts in patients with RDEB.Single-center phase 1 clinical trial conducted in the United States of 4 patients with severe RDEB with a measured area of wounds suitable for grafting of at least 100 cm2. Patients with undetectable type VII collagen keratinocyte expression were excluded.Autologous keratinocytes isolated from biopsy samples collected from 4 patients with RDEB were transduced with good manufacturing practice-grade retrovirus carrying full-length human COL7A1 and assembled into epidermal sheet grafts. Type VII collagen gene-corrected grafts (approximately 35 cm2) were transplanted onto 6 wounds in each of the patients (n = 24 grafts).The primary safety outcomes were recombination competent retrovirus, cancer, and autoimmune reaction. Molecular correction was assessed as type VII collagen expression measured by immunofluorescence and immunoelectron microscopy. Wound healing was assessed using serial photographs taken at 3, 6, and 12 months after grafting.The 4 patients (mean age, 23 years [range, 18-32 years]) were all male with an estimated body surface area affected with RDEB of 4% to 30%. All 24 grafts were well tolerated without serious adverse events. Type VII collagen expression at the dermal-epidermal junction was demonstrated on the graft sites by immunofluorescence microscopy in 9 of 10 biopsy samples (90%) at 3 months, in 8 of 12 samples (66%) at 6 months, and in 5 of 12 samples (42%) at 12 months, including correct type VII collagen localization to anchoring fibrils. Wounds with recombinant type VII collagen graft sites displayed 75% or greater healing at 3 months (21 intact graft sites of 24 wound sites; 87%), 6 months (16/24; 67%), and 12 months (12/24; 50%) compared with baseline wound sites.In this preliminary study of 4 patients with RDEB, there was wound healing in some type VII collagen gene-corrected grafts, but the response was variable among patients and among grafted sites and generally declined over 1 year. Long-term follow-up is necessary for these patients, and controlled trials are needed with a broader range of patients to better understand the potential long-term efficacy of genetically corrected autologous epidermal grafts.clinicaltrials.gov Identifier: NCT01263379.

• PUF60: a prominent new target of the autoimmune response in dermatomyositis and Sjogren's syndrome ANNALS OF THE RHEUMATIC DISEASES Fiorentino, D. F., Presby, M., Baer, A. N., Petri, M., Rieger, K. E., Soloski, M., Rosen, A., Mammen, A. L., Christopher-Stine, L., Casciola-Rosen, L. 2016; 75 (6): 1145-1151

  Abstract

  Autoantibodies are used clinically to phenotype and subset patients with autoimmune rheumatic diseases. We detected a novel 60 kDa autoantibody specificity by immunoblotting using a dermatomyositis (DM) patient's serum. Our objective was to identify the targeted autoantigen and to evaluate disease specificity and clinical significance of this new autoantibody.A new 60 kDa specificity was detected by immunoblotting HeLa cell lysates. The targeted autoantigen was identified as poly(U)-binding-splicing factor 60 kDa (PUF60) using (i) a human protein array and (ii) two-dimensional gel electrophoresis and liquid chromatography tandem mass spectrometry peptide sequencing. Anti-PUF60 antibodies were assayed by ELISA using sera from patients with primary Sjögren's syndrome (SS; n=84), systemic lupus erythematosus (SLE; n=71), DM (n=267), polymyositis (n=45), inclusion body myositis (n=45) and healthy controls (n=38).PUF60 was identified as a new autoantigen. Anti-PUF60 antibodies were present in 25/84 (30%) patients with SS, 6/71 (8.5%) patients with SLE and 2/38 (5.0%) control subjects (SS vs controls, p=0.002; SLE vs controls, p=0.711). Anti-PUF60 antibodies were present in 48/267 (18.0%) patients with DM versus 4/45 (8.9%) and 5/45 (11.1%) patients with inclusion body myositis and polymyositis, respectively. The antibody was significantly associated with anti-Ro52 antibodies, rheumatoid factor and hyperglobulinemia in the patients with primary SS. In patients with DM, the antibody was associated with anti-transcription intermediary factor 1 gamma seropositivity and Caucasian race.PUF60 represents a novel autoantigen in patients with SS and DM. PUF60 antibodies are associated with distinct clinical features and different immune responses in different diseases.

• JAK2-positive cutaneous myelofibrosis presenting as sclerosing extramedullary hematopoietic tumors on the scalp: case presentation and review of the literature. Journal of cutaneous pathology LeBlanc, R. E., Lester, L., Kwong, B., Rieger, K. E. 2015; 42 (11): 858-862

  Abstract

  We report the second case of cutaneous myelofibrosis with a documented JAK2 activating mutation involving the scalp of a 67-year-old woman with primary myelofibrosis in her marrow. In contrast to the previous case, the biopsy revealed extensive lesional collagen deposition and closely mimicked a fibrohistiocytic proliferation. Similar rare lesions occurring in the setting of myeloproliferative neoplasms have been called sclerosing extramedullary hematopoietic tumors. These entities appear histomorphologically and etiologically distinct from extramedullary hematopoiesis, and their diagnosis should prompt the workup for a myeloproliferative neoplasm in the absence of an antecedent diagnosis. The presence of the JAK2 mutation in our case confirmed that the lesions represented skin involvement by a neoplastic myeloid proliferation and not compensatory extramedullary hematopoiesis. Our patient died of disease several months following the appearance of her lesions, which is in keeping with other reports that suggest that cutaneous myelofibrosis may serve as an independent poor prognostic sign in otherwise advanced primary myelofibrosis. A review of the literature further emphasizes the importance of distinguishing this entity from mesenchymal neoplasms and acute myeloid leukemia involving the skin.

  Abstract

  This article acquaints the reader with disorders of the skin that might mimic systemic sclerosis but whose pathology is localized to the skin and/or has extracutaneous manifestations that are different than systemic sclerosis. These disorders include localized scleroderma (morphea), eosinophilic fasciitis, scleredema, scleromyxedema, nephrogenic systemic fibrosis, and chronic graft-versus-host disease. Particular emphasis is placed on clinical and histopathologic features that help the clinician differentiate between these disorders. Treatment options are briefly reviewed.

• Reconsidering the Diagnostic and Prognostic Utility of LN-2 for Undifferentiated Pleomorphic Sarcoma and Atypical Fibroxanthoma AMERICAN JOURNAL OF DERMATOPATHOLOGY Hollmig, S. T., Rieger, K. E., Henderson, M. T., West, R. B., Sundram, U. N. 2013; 35 (2): 176-179

  Abstract

  The topic of distinguishing atypical fibroxanthoma (AFX) from undifferentiated pleomorphic sarcoma (UPS), formerly malignant fibrous histiocytoma, is highly controversial. Although their clinical behavior is disparate, AFX and UPS commonly appear nearly identical on routine histopathologic examination. Although conceptually useful, subcategorization of UPS into superficial (confined to the dermis and subcutaneous tissue) and deep (involvement of fascia and deeper structures) types has not improved our ability to differentiate UPS from AFX. Numerous authors have purported LN-2 (CD74) immunopositivity as able to distinguish UPS from AFX and to predict those rare AFX likely to behave aggressively, although only a single prior study has been dedicated to evaluating this marker. We performed LN-2 staining of 14 AFX, 8 superficial UPS, and 65 deep UPS specimens using an identical protocol as described by prior authors. Of the 73 total UPS specimens, only 1 (1.4%) stained strongly with LN-2, as compared with 3 of 14 (21%) AFX (P = 0.012). One of 2 (50%) clinically aggressive AFX tumors that later exhibited both local recurrence and metastasis stained strongly for LN-2, whereas 2 of 12 (17%) of the more indolent tumors stained strongly with this marker (P = 0.40). Our data do not replicate prior reports of LN-2 as a sensitive and specific marker for UPS, or as indicative of prognosis for AFX, and therefore does not support the use of LN-2 as either a diagnostic or prognostic marker.

• ALK-negative systemic intravascular anaplastic large cell lymphoma presenting in the skin JOURNAL OF CUTANEOUS PATHOLOGY Rieger, K. E., POLIDORE, T., Warnke, R., Kim, J. 2011; 38 (2): 216-220

  Abstract

  Systemic cases of the CD30-positive T-cell neoplasm, anaplastic large cell lymphoma (ALCL), are typically anaplastic lymphoma kinase (ALK)-positive. The failure to express ALK protein has been shown to portend a worse prognosis. We describe a case of ALK-negative systemic ALCL that presented as a violaceous plaque on the scalp of a 79-year-old man. Interestingly, the neoplastic cells were confined largely within vascular spaces, a configuration that is exceedingly rare in the skin and is more typically seen with intravascular large B-cell lymphoma. In addition, bcl-2 immunohistochemical staining was strongly positive in this case, which may portend a more aggressive clinical course. To our knowledge, this report represents the first case of an ALK-negative ALCL to present intravascularly in the skin. Therefore, the recognition of systemic anaplastic T-cell lymphoma present within the intravascular spaces is important to avoid misdiagnosis.

• Recurrence rates associated with incompletely excised low-risk nonmelanoma skin cancer JOURNAL OF CUTANEOUS PATHOLOGY Rieger, K. E., Linos, E., Egbert, B. M., Swetter, S. M. 2010; 37 (1): 59-67

  Abstract

  Reported recurrence rates for transected nonmelanoma skin cancer (NMSC) vary widely, and few studies have addressed recurrence of tumors followed clinically or treated with nonsurgical modalities.Retrospective review of dermatopathology records from January 1999 to January 2005 was conducted to identify biopsies or excision specimens with histologically transected basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) which were not subsequently excised. Patient and tumor characteristics associated with recurrence were analyzed in a subgroup of patients with predominantly 'low-risk' and/or minimally transected NMSCs. Prospective follow up was performed through March 31, 2008. Data was analyzed with Chi-square and Fishers exact tests and multivariate logistic regression.Of 376 transected NMSCs, 27 (7.2%) recurred, including 20 (9%) of 223 BCCs and 7 (4.6%) SCCs in situ of 153 SCCs. The overall recurrence rate of the 124 minimally transected NMSCs was even lower (5.6%). Multivariate logistic regression identified three significant predictors of recurrence: tumor location on the head and neck (p = 0.041), tumor size (p = 0.00741) and superficial subtype of BCC (p = .035).Although surgical excision of NMSC remains the standard of care, observation or nonsurgical treatment may be acceptable in many cases of incompletely excised low-risk or minimally transected NMSCs.

• Toxicity from radiation therapy associated with abnormal transcriptional responses to DNA damage PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA Rieger, K. E., Hong, W. J., Tusher, V. G., Tang, J., Tibshirani, R., Chu, G. 2004; 101 (17): 6635-6640

  Abstract

  Toxicity from radiation therapy is a grave problem for cancer patients. We hypothesized that some cases of toxicity are associated with abnormal transcriptional responses to radiation. We used microarrays to measure responses to ionizing and UV radiation in lymphoblastoid cells derived from 14 patients with acute radiation toxicity. The analysis used heterogeneity-associated transformation of the data to account for a clinical outcome arising from more than one underlying cause. To compute the risk of toxicity for each patient, we applied nearest shrunken centroids, a method that identifies and cross-validates predictive genes. Transcriptional responses in 24 genes predicted radiation toxicity in 9 of 14 patients with no false positives among 43 controls (P = 2.2 x 10(-7)). The responses of these nine patients displayed significant heterogeneity. Of the five patients with toxicity and normal responses, two were treated with protocols that proved to be highly toxic. These results may enable physicians to predict toxicity and tailor treatment for individual patients.

• Portrait of transcriptional responses to ultraviolet and ionizing radiation in human cells NUCLEIC ACIDS RESEARCH Rieger, K. E., Chu, G. 2004; 32 (16): 4786-4803

  Abstract

  To understand the human response to DNA damage, we used microarrays to measure transcriptional responses of 10 000 genes to ionizing radiation (IR) and ultraviolet radiation (UV). To identify bona fide responses, we used cell lines from 15 individuals and a rigorous statistical method, Significance Analysis of Microarrays (SAM). By exploring how sample number affects SAM, we rendered a portrait of the human damage response with a degree of accuracy unmatched by previous studies. By showing how SAM can be used to estimate the total number of responsive genes, we discovered that 24% of all genes respond to IR and 32% respond to UV, although most responses were less than 2-fold. Many genes were involved in known damage-response pathways for cell cycling and proliferation, apoptosis, DNA repair or the stress response. However, the majority of genes were involved in unexpected pathways, with functions in signal transduction, RNA binding and editing, protein synthesis and degradation, energy metabolism, metabolism of macromolecular precursors, cell structure and adhesion, vesicle transport, or lysosomal metabolism. Although these functions were not previously associated with the damage response in mammals, many were conserved in yeast. These insights reveal new directions for studying the human response to DNA damage.
