Multiple Penile and Scrotal Schwannomas in an Adult Patient: A Case Report.

Abstract

Introduction: Schwannomas originate from the peripheral nerve sheaths and are mainly detected in the head, neck, or extremities. They are rarely encountered in the penoscrotal region.

Case presentation: Herein, we present a case of a penoscrotal schwannoma diagnosed and successfully treated in our center. A 40-year-old patient with a history of resection of a dorsal penile schwannoma presented with multiple nodular lesions at the scrotum, penile shaft, and radix, which were first noticed 5 years before his current presentation. He complained about penile pain and dyspareunia. Magnetic resonance imaging was performed for preoperative diagnosis. All nodular lesions were resected while preserving the neurovascular structures. The histopathological examination revealed benign lesions. The patient's complaints were resolved, and there was no recurrence during the 1-year follow-up.

Conclusion: The primary treatment is surgical excision. The patients need close follow-up regarding the risks of recurrence and malignant transformation.
