Cervical cancer is the most common malignancy of the female genital tract in Korea. The most common histologic type of cervical cancer is squamous cell carcinoma. The simultaneous occurrence of histologically distinct squamous cell carcinoma of the cervix and invasive adenocarcinoma of the cervix is extremely unusual. We have experienced two cases of synchronous squamous cell carcinoma and adenocarcinoma of the uterine cervix. We report these cases with a brief review of the literature.
