Squamous cell carcinoma of the vagina is a potentially invasive type of cancer that forms in the tissues of the vagina. Though uncommon, squamous cell cancer of the vagina (SCCV) is the most common type of vaginal cancer. It is further subdivided into the following subtypes: keratinizing, nonkeratinizing, basaloid, and warty. It forms in squamous cells, the thin, flat cells lining the vagina. SCCV accounts for approximately 85% of vaginal cancer cases and initially spreads superficially within the vaginal wall. It can later invade other vaginal tissues, but it spreads slowly. This carcinoma can metastasize to the lungs, and less frequently in liver, bone, or other sites. SCCV has many risk factors in common with cervical cancer and is similarly strongly associated with infection with oncogenic strains of human papillomavirus (HPV).
