Abstract
Primary lymphoma involving the prostate gland is rare. It accounts for 0.09 % of prostatic malignancies [1]. It commonly presents in the seventh decade with Lower Urinary Tract Symptoms (LUTS). Diffuse large B cell lymphoma is the common pathological variant [2]. Chemotherapy and radiotherapy are the common modalities of treatment and the overall prognosis is poor [2]. We present a 26 year old HIV infected patient - on anti-retroviral therapy who presented with acute renal failure and grossly enlarged prostate. Prostate biopsy with immuno-histochemistry confirmed the diagnosis of Peripheral T-cell lymphoma. He was treated with Adriamycin based chemotherapy and radiotherapy. We report this case in view of the rarity the tumor, younger age at presentation than that is available in literature and the pathological variant not reported in primary prostatic lymphoma.
