Lymphomas of the urinary tract

OBJECTIVES: The present study discusses both primary and secondary malignant lymphoreticular proliferative tumors of the urinary tract. METHODS: Two patients with urinary tract involvement are described: one female and one male with bladder and prostate involvement, respectively. RESULTS: Both cases presented clinical features that were not distinct from those of other tumors of the urinary tract. CONCLUSIONS: The anatomopathological study is essential to the differential diagnosis of urinary tract involvement from non-Hodgkin lymphoma and discards other extralymphatic conditions.
