Hepatosplenic γδ T-cell lymphoma is a rare histologic type of peripheral T-cell lymphomas, clinically characterized by predominant involvement of liver and spleen, no or little adenopathy, and an often aggressive course. We report a case of bone marrow involvement of hepatosplenic γδ T-cell lymphoma in a 21- year-old woman who presented with fever, anemia, thrombocytopenia, and hepatosplenomegaly. A lymphoma was found subsequently by bone marrow biopsy and computed tomography scan of
the abdomen and pelvis. Immunologic characterization of lymphoma cells in bone marrow revealed positivity for CD2, CD3, and CD16/56, and negativity for CD4, CD5, CD7, CD8, CD34, and terminal deoxynucleotidyl transferase (TdT). Conventional cytogenetic studies revealed the presence of isochromosome 7q. Using the PCR-SSCP technique, monoclonal gene rearrangement of the T-cell receptor gamma chain was demonstrated. Thus, we could make a confirmatory diagnosis as hepatosplenic γδ T-cell lymphoma.
