Endometrial carcinoma arising in one horn of a didelphys uterus

Abstract

Objective: Endometrial cancer in uterine anomalies is very rare. Currently, few cases with endometrial cancer coexistent with didelphys uterus are described. We present a case of a patient with carcinoma in one only horn of a didelphys uterus. Case report: A 50-year-old woman presented with abnormal uterine bleeding. Uterine anomaly was uncertain on initial clinical examination and pelvic ultrasonography. The MRI study showed double uterus and cervixes, a uterine didelphys was suspected. Preoperative histology from curettage described endometrioid adenocarcinoma. The patient underwent laparoscopic hysterectomy with surgical staging. Macroscopic examination revealed a didelphys uterus, and the final histology confirmed the diagnosis of uterine cancer. Conclusion: The coincidence of uterine malignancies and uterine anomalies is rare; however, it should be aware of uncertain diagnosis and delaying of treatment.
