title: Nephrogenic adenoma.
abstract: Nephrogenic adenoma is an uncommon, benign, apparently metaplastic response of urothelium to chronic infection or irritation. Endoscopically, these lesions easily can be mistaken for malignant tumors, and their scarcity only heightens the possibility of this error. A case report of nephrogenic adenoma accompanied by endoscopic photographs is presented to improve awareness and avoid inappropriate therapy.
