ABSTRACT
ABSTRACT Primary mucosal malignant melanoma of the nasal cavity is a rare tumor with aggressive behavior and a dismal prognosis. An extremely rare tumor that accounts for 0.7% to 1% of all melanomas in Caucasian populations and between 4% and 8% of malignant tumors of the nasal cavity and paranasal sinuses. Taking into account the rarity, it is important to note that malignant melanoma should be considered when making a differential diagnosis of tumors of the nose and paranasal sinuses. Two cases of primary malignant melanoma of the nasal cavity both arising in females, one in a 60-year-old and the other in a 64-year-old, both of whom presented with nasal obstruction and brief symptomatic epistaxis are being presented here. The diagnosis being confirmed by a histopathological examination along with an immunohistochemical analysis by using S100 and HMB45.
