Malignant lymphoma with genitourinary symptoms

Two cases are reported of patients with widespread intra-abdominal malignant lymphoma who althoug they initially presented with urologic complaints had no evidence of direct genitourinary involvement. Transrectal biopsy established the diagnosis in both cases. This unusual presentation of lymphoma is discussed together with a review of urologic involvement. The necessity for accurate diagnosis is stressed since effective treatment with radiation and chemotherapy is available.
