The epithelium of the cervical uterus was atypical upon biopsy. DIAGNOSES: Histological and immunochemical tests confirmed a diagnosis of endometrial carcinoma concomitant with cervical adenocarcinoma. INTERVENTIONS: She underwent laparoscopic staging surgery. OUTCOMES: The patient fully recovered with only surgery. LESSONS: Endometrial carcinoma concomitant with cervical adenocarcinoma is very rare. It is imperative to schedule adequate examination, and to perform careful preoperative diagnosis and appropriate treatment to minimize relapse.
