title: Nephrogenic adenoma: benign proliferative lesion of urothelium.
abstract: Three new cases of a rare benign proliferative lesion of the urothelium (nephrogenic adenoma) are hereby added to the existent 58 reported cases. All 3 lesions occurred in the bladder. Two of the 3 cases presented with a history of surgical interventions on the bladder, and the third patient had a history of chronic cystitis and pyelonephritis, and was on chronic dialysis. Diagnosis was made on histologic examination of cystoscopic biopsy of the lesions. Transurethral resection and/or fulguration was the treatment of choice. There was no recurrence of the lesions on follow-up cystoscopic examination.
