Endocervicosis is considered a form of Mülleriosis affecting mainly the bladder and is comprised of endocervical-type glands and cysts. It has been rarely described in the uterine cervix where the extensive involvement of cervical and paracervical tissue poses the suspicion of malignancy, mostly minimal-deviation adenocarcinoma. We describe a case of cervical endocervicosis causing long-term symptoms leading to hysterectomy. We provide evidence that this pathology is associated with cesarean section similar with isthmocele. Its differential diagnosis is discussed.
