Vaginal melanoma  Vaginal melanoma is a rare malignancy that originates from melanocytes in the vaginal epithelium. It is also known as a melanocytic tumor or as a malignant melanoma. It is aggressive and infrequently cured. The median overall survival is 16 months. Vaginal melanoma accounts 5.5% of all vaginal cancers and only 1% of all melanomas diagnosed in women. Vaginal melanomas are frequently diagnosed in advanced stages of the disease. The prognosis is poor and the most important risk factor is the presence of lymph node metastases. This cancer most often develops on the lowest third of the vagina. It is darkly pigmented and of an irregular T-shape, but amelanotic melanomas have been describedin 7%. Melanoma of the vagina can be several centimeters in size. When the tissue is assessed, the histological characteristics include:  Other cancerous conditions arise from vaginal epithelium:  A biopsy should be obtained from all suspicious lesions and Immunocytochemistry can reveal positive results for S-110 protein, HMB 45 and melan A. Surgery represents the primary treatment modality. Chemotherapy may be ineffective, but checkpoint inhibitors and BRAF and MEK inhibitors have been recently tested in vaginal melanomas.
