title: A rare case of multiple schwannomas presenting with scrotal mass: a probable case of schwannomatosis.
abstract: We report a rare case of multiple schwannomas presenting with scrotal mass. In the present case, a scrotal schwannoma developed in a 66-year-old man with a history of brain tumor surgery. Investigating the patient's past history lead to the diagnosis as probable schwannomatosis. Patients with schwannomatosis are at increased risk of developing multiple schwannomas and these patients need regular surveillance. In this regard, the present case highlights the importance of thorough history taking in patients with scrotal schwannoma.
