Schwannoma of the dorsal nerve of the penis: case report and differential diagnoses

Abstract

Schwannomas are tumors that appear in the sheath that surrounds the nerves; they are formed of Schwann cells which form the myelin sheath in peripheral nerves. In this document, we report a case of Schwannoma of the dorsal nerve of the penis in a man 40-year-old male with no history of neurofibromatosis. Despite the abundant innervation of the penis, it is rare to find them in this location with < 50 cases reported in the literature. Its diagnosis is integrated based on physical examination and supported by imaging. The definitive diagnosis is obtained with histopathology with immunohistochemistry.
