Abstract:
Nephrogenic adenoma is a benign urothelial neoformation rare in children. It can be present in the entire urinary tract, being more common in the bladder and very infrequent in urethra. These metaplasic changes seem to be due to irritative stimulus to the epithelium, including lithiasis, previous surgery, permanent or repeated catheterization, infective diseases and chemotherapy and or radiotherapy. The diagnosis is established after biopsy and in most of the cases the treatment of choice consists of transurethral resection of the lesion. We report the case of a boy 11 years old who was diagnosed of Nephrogenic adenoma of prostatic urethra after cistoscopy for repetitive urethremorrhagia. The patient was managed conservatively and oral antibiotic therapy was administered being the patient asymptomatic and free of recurrence during the follow up.
