Schwannomas usually occur along the peripheral nerves but are very rare at the penis 1, 2. A 35-year-old man presented to our clinic seeking evaluation for a painless swelling on his penis. He had first noticed the mass 5 years before presentation; it gradually increased in size and recently interfered with sexual activity. Examination revealed a cordlike mass on the left lateral side which caused penis curvature (fig. 1). Ultrasonographic examination detected a 6.0 X 5.0 X 2.0 cm hypoechoic mass with irregular margins. A pelvic CT scan showed that the tissue was located beside the left corpus spongiosum with soft tissue density (fig. 2). The postoperative pathological diagnosis was benign plexi-form schwannoma.
