Urogenital involvement by malignant lymphomas.

Records of 1,068 patients with malignant lymphomas were reviewed from a more than 10-year interval for any evidence of lymphomatous involvement of the urogenital tract. Of the 1,068 patients 72 (6.7 per cent) had urologic findings related to lymphoma either at autopsy, radiographically or at operation. Of 400 cases 23 (5.8 per cent) with Hodgkin's and 49 of 668 cases (7.3 per cent) with non-Hodgkin's lymphoma had some evidence of urogenital involvement at some point in the course of the disease. In the total group reviewed the rate of involvement was low (6.7 per cent) and was essentially equal for patients with Hodgkin's and non-Hodgkin's lymphomas. We herein illustrate various forms of urogenital tract problems encountered in patients with solid lymphatic tumors.
