Malignant melanoma of the left nasal fossa - case report.

Mucosal malignant melanoma is an extremely rare tumor of the nose, with an aggressive character, low prognosis and frequent recurrences. The authors present a case of a 60-year-old male patient, diagnosed five years ago with adenoid cystic carcinoma, for which he had surgery and radiotherapy, who was admitted in our Clinic with unilateral epistaxis and obstruction of the nasal cavity. Clinical exam revealed an obstructive polypoidal bleeding mass of the left nasal cavity. Biopsy was performed and the histopathological exam showed malignant mucosal melanoma. Wide local endoscopic surgery was practiced for two times in the last two years, and for now, there is no recurrence. Malignant melanomas are tumors with high mortality rate, which necessitate an early diagnosis and immediate treatment.
