Abstract

Primary mucosal malignant melanoma in the nasal cavity and paranasal sinus is rare, and it has predominance in elderly patients with poor prognosis. It may lead nasal obstruction and/or epistaxis. A 46-year-old man was admitted to the hospital with three months of epistaxis. A black mass filling left nasal cavity was found on endoscopic examination. Histopathology with immunohistochemical staining revealed malignant melanoma. He had surgical resection since he had no distant metastasis. In here, mucosal malignant melanoma is discussed with review of the literature.
