[Endometrioide-type cervical adenomyoma]

Abstract

Adenomyoma of the cervix is a rare, benign lesion. It is a localized form of adenomyosis, which is surrounded by a benign muscle proliferation forming a tumor similar to leiomyoma. Of the three histological variants of adenomyomas, the most frequent is the endocervical type. We present a case of a 34-year-old woman with a tumor in the lower uterine segment which enlarged during pregnancy, replacing the entire cervix and resulting in the occlusion of the endocervical canal. Ultrasound and tomography showed a mixed tumor pushing aside the uterus and bladder. Speculoscopy revealed that the tumor protruded towards the vaginal canal. Histopathological established the diagnosis of a cervical adenomyoma of the endometrioid type.
