Abstract
A 73-year-old woman, whose medical history reported radical hysterectomy and radiotherapy for squamous cell carcinoma of the cervix uteri 20 years earlier, was found to have an angiosarcoma of the vagina. The histological diagnosis was confirmed by immunohistochemical staining of tumor cells for factor VIH-related antigen and ultrastructurally defined vasoformative structures. Primary angiosarcoma of the vagina is quite rare and reported in only two published cases. The present case is a third in general, and the first report confirmed by light microscopy, immunohistochemical, and electronmicroscopy studies.
