Gamma-delta T-cell acute lymphoblastic lymphoma/leukemia: a report of a rare entity.

Gamma delta (γδ) T-cell acute lymphoblastic leukemia/lymphoma (T-ALL) is a rare, aggressive subtype of T-lymphoid leukemia that accounts for only 9-12% of all T-ALL cases. Herein, we report the case of an 8-year-old boy who presented with facial swelling, shortness of breath, and progressive cervical and axillary lymphadenopathy. Pathological examination, flow cytometry (Navios, Beckman Coulter ClearLLab 10C 10-color T-cell panel [containing FITC-labeled TCR γδ antibody]), chromosomal analysis, interphase FISH, and targeted DNA-based NGS (34-gene Illumina TruSeq Myeloid Panel) were performed.

Metastatic large-cell neuroendocrine carcinoma of the lung masquerading as a primary gallbladder carcinoma: A case report.

Gallbladder neuroendocrine carcinoma is rare, representing ~4% of all primary malignant gallbladder neoplasms. We report the case of a 75-year-old female who presented for radiologic restaging for lung adenocarcinoma diagnosed elsewhere, demonstrating a hypermetabolic gallbladder mass. With concern for a gallbladder primary, radical cholecystectomy followed.

The role of splenectomy in management of splenic B-cell lymphomas.

Introduction: Splenic B-cell lymphomas are rare and understudied entities. Splenectomy is frequently required for specific pathological diagnosis in patients with splenic B-cell lymphomas other than classical hairy cell leukemia (cHCL), and can be effective and durable therapy. Our study investigated the diagnostic and therapeutic role of splenectomy for non-cHCL indolent splenic B-cell lymphomas.

A Rare Case of Renal Thrombotic Microangiopathy and Focal Segmental Glomerulosclerosis Secondary to Plasma Cell Leukemia.

Plasma cell dyscrasias are a subset of hematological malignancies involving the production of monoclonal immunoglobulins. This spectrum of disorders includes asymptomatic conditions such as monoclonal gammopathy of unknown significance as well as extremely aggressive malignancies such as plasma cell leukemia. Monoclonal gammopathies are occasionally associated with renal failure, which can occur via many pathophysiological processes.
