Nephrogenic adenoma is an uncommon, benign, tumor-like lesion within the urothelial mucosa of the urinary tract. To date, the etiology has been considered to be metaplastic change of the urothelial cells to renal tubular cells. The theory, however, that nephrogenic adenoma arises from implantation of renal tubular cells into the urinary bladder is the current focus of attention. Cystoscopic findings of nephrogenic adenoma often resemble those of urothelial carcinoma, and recurrence following transurethral resection has been reported. Accordingly, postoperative follow-up examinations are strongly recommended.
