The median age was 66 years. Clinical signs and symptoms were due to lower urinary tract obstruction resulting from a diffusely enlarged prostate. Prostate biopsies revealed diffuse large B-cell non-Hodgkin’s lymphoma. The therapeutic modalities included prostatectomy, radiotherapy and chemotherapy.RESULTS Extraprostatic involvement at various sites became evident in 19 of the 29 patients after diagnosis. Ten patients died from lymphoma with a median survival of 23 months (range, 2-30 months). Seven patients were alive up to 60 months.CONCLUSION Malignant lymphoma involving the prostate was rare and has a rather poor prognosis. Prognosis related to the patient age, histologic type, and treatment or clinical stage of the disease at presentation.
