Complete resection of penile schwannoma without sexual dysfunction
Özet
Schwannomas originate from the neural sheaths of peripheral nerves, and are frequent in the head, neck, extremities, mediastinum, and retroperitoneum. In spite of the rich innervations of the external genitalia, schwannomas are rare in the penis. We reported a case of penile schwannoma with clinical presentation and management. A sexually active 28-year-old man presented with a painless, slowly growing, nodular mass on the dorsum of penile shaft of at least 2 years' duration. A nodular fixed mass about 4.0 cm in length was palpated on the dorsal aspect of the proximal penile shaft. Preoperative diagnosis was made with ultrasonography and magnetic resonance imaging. The mass was completely removed with preserving dorsal penile neurovasculature. Pathologic examination of the mass showed a benign schwannoma. No erectile dysfunction and penile curvature were observed over the six months after the surgery. Schwannoma of the penis is a rare benign tumor that can be diagnosed with the help of ultrasonography and magnetic resonance imaging. It should be treated by complete resection. Erectile function can be preserved by preserving dorsal penile neurovasculature.
