Schwannoma of the penis: a case report

A 39-year-old man presented with a painless nodule on the left dorsal aspect of root of the penile shaft, which was first noticed in childhood, but had been left untreated. This nodule gradually increased in size, and he visited the Department of Urology. He had no urinary symptoms, and there was no interference with sexual intercourse. Upon physical examination, we observed a well-defined, firm 20 mm nodule on left dorsal aspect of root of the penile shaft that was tender and had no adhesion to overlying skin. There were no other abnormalities; in particular, no other similar lesions could be found. We suspected a benign tumor of the penis and removed it. Histological examination revealed a benign schwannoma composed of Antoni A and Antoni B areas.
