A case of primary amelanotic melanoma of the vagina diagnosed in scraping smear is described. A 64-year-old woman complained of vaginal bleeding with a $2.5 imes2cm$ sized, fungating mass on the right lateral vaginal wall near the introitus for 2 months. Scraping smears from the mass showed scattered individual tumor cells with single, bi- or multi-nucleated eccentric nuclei having prominent macrouucleoli and occasional intranuclear inclusions. The cytoplasm was plump and cyanophilic with a indistinct rim. No melanin pigment was identified. Characteristic cytologic features of this case were very helpful to exclude more common squamous cell carcinoma in the vagina, which was strongly suggested in biopsy specimen.
