Primary T-cell Lymphoma of the Uterine Corpus

Malignant lymphoma involving the genital tract is rare, and primary lymphoma of the uterus is even rarer. Immunohistochemically, most of the reported cases have been diffuse large cell lymphomas with a B-cell nature. Herein, we report an unusual case of uterine T-cell lymphoma in a 68-year-old woman. She suffered from fever, vaginal bleeding, and a huge mass in the lower abdomen. The initial clinical and histologic studies failed to indicate a cell type. We provide the clinical details of the case and discuss the diagnostic pitfalls.
