ALVAREZ ALVAREZ, C. et al. Primary non-Hodgkin large B-cell lymphoma of bladder: Report of a case. Actas Urol Esp [online]. 2005, vol.29, n.9, pp.902-904. ISSN 0210-4806.

Introduction: primary genitourinary lymphomas are uncommon. Among them, bladder lymphomas are extremely unusual tumors, with clinico-radiological features similar to urothelial carcinomas of bladder. Histopathological, immunohistochemical and molecular studies are compulsory for the diagnosis. We report a case of this tumor. Clinical case: An 80-year-old woman was admitted to our hospital with hematuria. Abdominal ultrasound and cystoscopy revealed an infiltrating bladder tumor involving the right lateral wall. After transuretral biopsy, a diagnosis of non-Hodgkin large B-cell lymphoma was made. Neither clinical symptoms nor radiological findings showed disseminated disease, indicating that the tumor was localized in the bladder. After chemotherapy, the patient is disease-free after 9 months follow-up. Comment: if a bladder tumor with uncommon histopathological features is found, lymphoma should be excluded, because chemotherapy avoids cystectomy.
