Solitary penile neurofibroma with erectile dysfunction.

Neurofibromas of the penis, although very rare, are often associated with neurofibromatosis type 1. Primary solitary neurofibromas of the penis are extremely rare. We describe a 37-year-old man with a solitary neurofibroma in the dorsum of the penis. The patient reported difficulty with sexual intercourse owing to a penile mass and erectile dysfunction. After surgical excision of the neurofibroma, he had no pain and a normal sensation of the penile glans, and his erectile dysfunction improved. At the present time, 26 months after surgery, there has been no evidence of tumor recurrence.
