Abstract:
Penile neoplasm is uncommon, and multiple penile schwannomas are even rarer. We report a case of a 37-year-old man with multiple schwannomas on the left side of the penis, which had been present for more than 10 years without significant enlargement during erection and had recently been associated with mild pain. Ultrasonography revealed several subcutaneous heterogeneous hypoechoic of penile, the larger of which was approximately 1.9 × 0.9 cm. The patient underwent penile mass excision, and pathology and immunohistochemistry confirmed that it was schwannoma. The patient was followed up for 3 years without recurrence or metastasis.
