Carcinosarcoma of the uterine cervix: a rare pathological finding originating from mesonephric remnants.

ABSTRACT

Carcinosarcoma of the uterine cervix is a very rare tumour that has been described in less than 70 cases in the literature. It is less common compared with carcinosarcoma of the uterine corpus and it can have two origins the Müllerian ducts and the mesonephric duct remnants. The association of mesonephric carcinoma with a sarcomatous component was reported in only 11 cases, including the following. We describe a case of a 64-year-old woman, presenting with vaginal bleeding and a cervical lesion reported as a sarcoma of endometrial stroma in the first biopsy. After exclusion of distant disease, she was submitted to radical surgery and the final histopathological examination showed a carcinosarcoma of the cervix with mesonephric origin.
