Abstract. Background: Primary melanoma of the vagina (PMV) is a rare entity. The prognosis of women with PMV is poor and there is no standardized therapy for this type of malignancy. We present the case of a 72-year-old womanwith PMV (cT2, pN0, M0 Melanoma is caused by the malignant transformation of pigment cells. Apart from the skin, pigment cells such as melanocytes are present in various mucosal linings such as those of the gastrointestinal, respiratory, and urogenital tracts (1). Thus, in addition to the common cutaneous locations, melanomas may also arise in mucosal areas of various organs. Cutaneous melanomas are estimated to be the sixth most common cancer entity among females in the US (2). In contrast, mucosal melanomas are rare and account for only 1.4% of all melanomas. Of note, gender plays an important role in the epidemiology of mucosal melanomas. With almost three cases per million women, which is half that for men, mucosal melanomas are significantly more often diagnosed among women (3). This gender gap is caused by the fact that genital tract mucosal melanomas are more common among women than they are among men, whereas extra-genital mucosal melanomas are evenly distributed between the sexes (3).In the female genital tract, the predominant location of melanoma is the vulva whereas the vagina is rarely affected (3). Specifically, the incidence of primary melanoma of the vagina (PMV) is about three cases per 10,000,000 women per year. Primary melanomas of the vulva are four to nine times more frequent than PMV (4, 5). PMV is typically diagnosed in elderly women at an advanced stage and is characterized by early recurrence and a poor prognosis (2). The 5-year overall survival rate for PMV is below 20% compared to around 45% for those with vulvar melanoma and >80% for those with cutaneous melanoma (2-6). This remarkable difference has been attributed to a variety of 6911 This Αrticle is freely accessible online.
