Most T-cell lymphomas arise from mature alpabeta T-cells and commonly involve the nodes. Lymphomas bearing the gamadelta T-cell receptor (TCR) are very rare, and involve the lymph nodes minimally, if at all. Hepatosplenic gamadelta T-cell lymphoma is a recently identified, rare entity in which lymphoma cells bearing the gamadelta TCR infiltrate the sinusoids of the liver, splenic red pulp, and bone marrow. Its leukemic transformation is even more rare. Recently, we experienced a case of hepatosplenic gamadelta T-cell lymphoma in a 19-year-old woman who presented with epigastric pain, fever, massive splenomegaly, andpancytopenia. The splenectomy specimen and excisional biopsy of the liver revealed the infiltration of atypical T lymphocytes with the immunophenotypic markers of CD3 (+), CD45RO (pan-T antigen) (+), TIA-1(+), CD4(-),CD8 (-), CD56 (-), and S100 (-) in the sinusoids of the liver and splenic red pulp. Polymerase chain reaction (PCR) showed that these cells had the expression of the TCR gama gene rearrangements. Though the pancytopenia had improved after the splenectomy, the response of chemotherapy was transient. Her disease progressed rapidly and she expired in the leukemic phase. We report a case of hepatosplenic gamadelta T-cell lymphoma that developed in a young woman, along with a brief review of the literature.
