  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.
