  • Subcutaneous Panniculitis-Like T-Cell Lymphoma: Pediatric Case Series Demonstrating Heterogeneous Presentation and Option for Watchful Waiting PEDIATRIC BLOOD & CANCER Johnston, E. E., LeBlanc, R. E., Kim, J., Chung, J., Balagtas, J., Kim, Y. H., Link, M. P. 2015; 62 (11): 2025-2028

    Abstract

    Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) and primary cutaneous gamma delta T-cell lymphoma (PCGD-TCL) were initially both classified as subcutaneous panniculitis-like T-cell lymphoma. In 2008, SPTCL with alpha-beta T-cell receptor subtype was separated from primary cutaneous gamma delta T-cell lymphomas (PCGD-TCL). We report four pediatric cases that demonstrate the heterogeneity of each disease and show that PCGD-TCL in children can have an indolent course, whereas SPTCL can behave aggressively. Three patients had spontaneous, durable remissions without treatment, whereas the one patient with disease progression was treated successfully. Watchful waiting may thus be appropriate for initial management of children.

  • Therapeutic Complications in a Patient With High-Risk Acute Lymphoblastic Leukemia and Undiagnosed Hereditary Hemochromatosis PEDIATRIC BLOOD & CANCER Balagtas, J. M., Dahl, G. V. 2012; 58 (1): 101-103

    Abstract

    Hereditary hemochromatosis (HH) is an autosomal-recessive disorder of iron metabolism that most commonly manifests in the fourth or fifth decade of life. Here, we describe a 14-year-old male who presented with high-risk acute lymphoblastic leukemia and previously undiagnosed HH. His treatment course was remarkable for significant therapeutic complications, including iron overload, hepatic failure, cardiac dysfunction, and death. Postmortem testing revealed homozygosity for the C282Y mutation, confirming the diagnosis of HH. Since HH mutations occur commonly in select populations, screening patients with leukemia for HH may better inform treatment decisions regarding chemotherapy, transfusions, and/or iron chelation therapy.

  • Liposomal amphotericin B associated with severe hyperphosphatemia PEDIATRIC INFECTIOUS DISEASE JOURNAL Sutherland, S. M., Hong, D. K., Balagtas, J., Gutierrez, K., Dvorak, C. C., Sarwal, M. 2008; 27 (1): 77-79

    Abstract

    We report 4 patients who developed hyperphosphatemia while receiving liposomal amphotericin B to treat an invasive fungal infection. Resolution of the hyperphosphatemia occurred after transition to amphotericin B lipid complex. This phenomenon may occur more commonly in patients with mild to moderate renal insufficiency.
