A case of a primary amelanotic melanoma of the vagina is reported. The patient was a 58-year-old Japanese female. A polypoid tumor was found on the lateral wall of the vagina and a cytologic examination of a scraping showed a few large atypical cells with cleaved nuclei and intranuclear vacuoles. A lateral junctional spread was histologically observed and stage II melanosomes were found in the cytoplasm. Two years after a radical operation, the patient died of a widespread melanotic metastases. The authors survey the number of incidences of malignant melanoma in the female genital organ. In Japanese women, melanoma is seen more frequently in the vagina than in the vulva, which is quite the opposite in cases of malignant melanomas of the genital organs in women of the United States and Europe.

UI	MeSH Term	Description	Entries
D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D009092	Mucous Membrane	An EPITHELIUM with MUCUS-secreting cells, such as GOBLET CELLS. It forms the lining of many body cavities, such as the DIGESTIVE TRACT, the RESPIRATORY TRACT, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose CONNECTIVE TISSUE, and an outer layer (muscularis mucosae) of SMOOTH MUSCLE CELLS that separates the mucosa from submucosa.
