Malignant melanoma aries from melanocyte, which has the ability to synthesize the pigment melanin. Melanocytes are derivations of neural crest cells and widely distributed throughout all cutaneous and mucosal surfaces. Overall, 20% of all malignant melanomas arise in the head and neck, of which only 10% affect the mucous membranes. Less than 1% of all malignant melanomas affect the nasal cavity. The authors experienced a case of primary malignant melanoma originated in left nasal cavity and paranasal sinus, and the patient had been treated by wide excision of the tumor with Weber-Furguson approach and postoperative irradiation. We report a case of primary malignant melanoma on the nasal cavity and paranasal sinus of 49 years old female patient with review of literature.
