Choriocarcinomas usually occur within the body of the uterus during reproductive years. On rare occasions they may occur abnormally in relation to place and time. Primary choriocarcinomas of the uterine cervix are extremely rare. They usually occur in a latent period of six months to two years after the preceding pregnancy, and present with disfunctional vaginal bleeding. Theoretically, there are three mechanisms for the development of the cervical choriocarcinoma: 1) the patient initially had a cervical pregnancy and this was followed by malignant transformation; 2) the cervical choriocarcinoma may be a metastasis from the primary tumor of the corpus, which had disappeared; 3) the development of cervical choriocarcinoma was due to the transport of chorionic cells from the preceding pregnancy as emboli, which stayed dormant and, later, gave rise to malignant transformation. Total abdominal histerectomy and posterior chemotherapy are recommended. We report a case of a 34-year-old woman, with vaginal bleeding six months after a term pregnancy, which had a hemorrhagic cervical mass and high b-HCG blood levels. The histopathology showed a tumor with a malignant sincicio and citotrophoblastic components involving only the uterine cervix. Our case is one of an ectopic choriocarcinoma and we believe that its development is due to the transport of chorionic cells from the preceding pregnancy and later gave rise to malignant transformation.
