A single-center retrospective review of pediatric cases of progressive transformation of germinal centers.

Background: Progressive transformation of germinal centers (PTGC) is a rare diagnosis characterized by asymptomatic lymph node enlargement. It has previously been associated with lymphoma, autoimmune conditions, and lymphoproliferative diseases in small pediatric case series.

Procedures: We conducted a single-center retrospective review of pediatric cases of PTGC diagnosed at our institution by hematopathologists from 2000 to 2020.

The American Society of Pediatric Hematology Oncology workforce, productivity, and fellowship assessment: Current state of the workforce.

The American Society of Pediatric Hematology Oncology conducted follow-up workforce surveys in 2017 and 2021 as well as a Pediatric Hematology Oncology Fellowship Program Directors Survey in 2020 to provide an updated review of the current workforce. We provide a comprehensive review and analysis of these results with the goal to provide better understanding of the current landscape in pediatric hematology oncology.

Characteristics and outcomes of pediatric oncology patients at risk for guardians declining transfusion of blood components.

Background: Transfusion of blood products is a necessary part of successful delivery of myelosuppressive regimens in pediatric cancer. There is a paucity of literature characterizing outcomes or management of pediatric patients with cancer when transfusion is declined.

Aims: The objective of this paper is to describe the clinical characteristics, care, and outcomes of patients with cancer at risk for declining transfusion.

Hematogones With Lambda Light Chain Restriction in a 4-Year-Old Boy With Burkitt Lymphoma: A Potential Diagnostic Pitfall.

Hematogones are immature normal B cell precursors with a characteristic immunophenotype profile on flow cytometry that typically do not express surface immunoglobulin light chains. In this report, we describe a case in which the hematogones exhibit light chain restriction. Our patient was a 4-year-old boy with a complicated medical history involving treatment for a presumed bilateral Wilms tumor of the kidney that on later resection was diagnosed as Burkitt lymphoma.

Successful treatment with modified CHOP-rituximab in pediatric AIDS-related advanced stage Burkitt lymphoma.

Burkitt lymphoma is the most common AIDS-related lymphoma (ARL) in childhood. The major issues in adult and pediatric ARL include identifying the optimal chemotherapy regimen and the concurrent treatment of both rituximab and highly active anti-retroviral therapy (HAART). We present a case of advanced stage Burkitt lymphoma in an 8-year-old female with acquired immunodeficiency syndrome (AIDS), who was successfully treated with a 3 month course of modified CHOP-R (cyclophosphamide, daunorubicin, vincristine, prednisone, and rituximab) and HAART therapy.
