Mucosal melanoma

Mucosal melanoma is a rare condition characterized by a melanoma of the mucous membranes. This subtype is associated a worse prognosis than those arising from the skin.[1]:696[2] Mucosal melanomas occur in the head and neck (55%), anorectal (24%) and vulvovaginal region (18%), and in the urinary tract (3%).[3] Based on the histopathologic and clinical features, melanomas of the vulva and vagina are often considered a separate disease entity. [4] The prognosis of vulvovaginal melanomas is poor, especially for vaginal melanomas and has not improved over the last decades. [5]
