Mucosal melanoma invades mucosal tissue in the body including the nasal cavity, lining of sinuses and mouth, the GI tract, vagina, anus, and other areas. Mucosal melanoma accounts for about 1% of all melanoma diagnosis.
Unlike cutaneous melanoma, mucosal melanoma is not believed to be caused by exposure to the sun or other sources of ultraviolet radiation.
Mucosal melanoma is generally diagnosed at a later stage of disease and because of this it has a worse prognosis compared to other types of melanoma.1Learn more about melanoma staging or treatment.
