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.

“…Patients consult for a progressive increase in penile swelling [5,6] or a disorder during intercourse [1] as described in the observation. These tumors occur at any age and mainly between 30 and 60 years [1,[5][6][7][8]. The differential diagnosis must be made with all benign or malignant tumors of the penis including the keloid of the penis.…”

Introduction: Schwannoma of the glans is a rare clinical entity. The diagnosis is histological. Treatment is surgical, with complete excision. The authors report this rare case encountered at the University Hospital of Libreville in order to identify its clinical and therapeutic characteristics. Observation: Mr. I.B, 50 years old, with no medical-surgical history, consulted for swelling of the glans evolving for 06 years, preventing coitus. He reported a notion of poor healing from an acorn sore after the trouser fly was closed. The diagnostic suspicion was a glans keloid. A complete resection was performed. Histologic examination favored a glans schwannoma. Healing was effective on D7 postoperatively. Erectile functions have been preserved. Conclusion: The glans schwannoma is rare. Surgical treatment gives good results.

“…Penile plexiform schwannomas are extraordinarily rare with only 2 cases having been identified so far out of the 34 published cases of penile schwannomas. Recently, in 2017, Kumar U et al reported an uncommon presentation of sizeable penile schwannoma mimicking a scrotal mass in a 16-year-old boy [8].…”

Schwannomas are benign, encapsulated neurogenic tumors which present in diverse histological subtypes despite the limited variety of their cellular constituents. These include the cellular, ancient, cystic, epithelioid, melanotic, psammomatous, schwannoma with pseudoglandular elements, and plexiform varieties. The plexiform schwannoma (PS) represents 4.3% of all schwannomas. These lesions are commonly encountered in the head and neck region and are extremely rare in the penis. To the best of our knowledge only 34 cases of penile schwannomas have been reported and this is the 3rd case of plexiform penile schwannoma. A 39-year-old patient presented to our andrology outpatient clinic complaining for two painful penile nodules. The lesions were located on the dorsum of the penile shaft. His medical history was insignificant for penile trauma and sexual transmitted diseases. The masses measured 2x1 cm and 0.5x1 cm. After sonographic and magnetic resonance evaluation the patient was admitted to theatre and underwent topical resection of the lesions. Histopathology revealed plexiform schwannoma. Postoperatively, penile tenderness and hyperesthesia ensued which was managed with pregabalin administration and topical corticosteroids. Plexiform schwannomas are rare in the penile region. Surgical excision is inevitably the only way to diagnose and treat the lesions. They must be differentiated by a variety of malignant and benign clinical conditions. Topical excision suffices for oncological control and allows for acceptable functional outcomes.
