Primary malignant melanoma of the vagina

Primary malignant melanoma of the vagina is a rare gynaecological neoplasm with an aggressive course of disease. Although not many cases have been reported in the literature, its manifestations appear to be fairly consistent. The challenge comes in knowing how to approach this cancer clinically, since information about its staging and treatment is limited. In this report, we present a case of an 84-year-old postmenopausal woman in whom a suspicious vaginal lesion was discovered incidentally during a procedure. Wide local excision was carried out at a later date and histopathology confirmed a malignant melanoma of the vagina contained locally with no radiological finding of distant metastases. No additional treatment was given, and three monthly follow-ups were arranged for this patient. We review the literature and briefly discuss the epidemiology, treatment approaches, prognostic factors and expected outcomes of this rare disease.
