Mucosal melanoma (cancer of skin pigment cells or lining tissue of the nose and sinuses) of the nasal cavity represents only one to two percent of all melanomas, but is the most common site of occurrence outside of sun-exposed areas of the skin. Like most tumors of the sinuses, melanoma usually begins in the maxillary sinuses (cheek bone sinuses) and ethmoid sinuses (between the eyes and nose). The symptoms of mucosal melanoma include frequent bloody nose, nasal discharge and drainage. Rarely, because of orbital (eye socket) involvement there may be proptosis (bulging of the eyeball outward) and eye pain.
