Surgical excision of Genitourinary neurofibromatosis complicated by enlarged scrotum and penis: A case report.

Neurofibromatosis, the most common neurocutaneous syndrome, is characterized by numerous neural crest tumors and abnormal skin pigmentation. Genitourinary neurofibromatosis in children is extremely rare and bladder involvement is relatively common. Few cases of neurofibromatosis reported so far involve external genitalia. Here we present a 17-year-old boy with genitourinary neurofibromatosis who has a significantly enlarged penis and scrotum. Although the patient had no obvious symptoms, a diagnosis and surgical evaluation were necessary due to the underlying malignancy and the patient's discomfort.
