Overview
Vaginal cancer is a type of cancer that forms in the tissues of the vagina. The vagina leads from the cervix (the opening of the uterus) to the outside of the body.
Carcinomas of the vagina are uncommon tumors comprising 1% to 2% of gynecologic malignancies. They can be effectively treated, and when found in early stages, are often curable. The histologic distinction between squamous cell carcinoma and adenocarcinoma is important because the two types represent distinct diseases, each with a different pathogenesis and natural history. Squamous cell vaginal cancer (approximately 85% of cases) initially spreads superficially within the vaginal wall and later invades the paravaginal tissues and the parametria. Distant metastases occur most commonly in the lungs and liver.
Adenocarcinoma (approximately 15% of cases) has a peak incidence between 17 and 21 years of age and differs from squamous cell carcinoma by an increase in pulmonary metastases and supraclavicular and pelvic node involvement. Rarely, melanoma and sarcoma are described as primary vaginal cancers. Adenosquamous carcinoma is a rare and aggressive mixed epithelial tumor comprising approximately 1% to 2% of cases.
