title: Mantle cell lymphoma of the prostate.
abstract: Lymphoma of the prostate, either primary or secondary, is very rare. We report the case of an 82-year-old man with symptoms of bladder outlet obstruction presumably due to benign prostate hyperplasia (BPH). He underwent an uneventful transurethral resection of the prostate. Pathological review of the resected tissue demonstrated substantial infiltration by an atypical lymphoid infiltrate positive for CD20, BCL2, CD5, kappa light chain and cycline D1. Histology and immunoprofile were consistent with mantle cell lymphoma.
