A squamous cell carcinoma arising from the cervical epithelium. It usually evolves from a precancerous cervical lesion. Increased numbers of sexual partners and human papillomavirus (HPV) infection are risk factors for cervical squamous cell carcinoma. The following histologic patterns have been described: conventional squamous cell carcinoma, papillary squamous cell carcinoma, transitional cell carcinoma, lymphoepithelioma-like carcinoma, verrucous carcinoma, condylomatous carcinoma and spindle cell carcinoma. Survival is most closely related to the stage of disease at the time of diagnosis.
