Endometrial carcinoma in a single horn of a bicornuate uterus: A case report.

We discuss the diagnosis and the management of endometrial carcinoma in a single horn of bicornuate uterus in a 64-year-old woman as a case report. The case underwent laparoscopic radical hysterectomy and bilateral iliac lymphadenectomy. The gross examination of the uterus revealed a bicornuate uterus with a greater horn of 12 × 9 × 8 cm and a smaller horn of 10 × 3 cm. The cavity of the greater horn showed a neoplastic growth of 10 cm with infiltration of about 1,8 cm of the myometrium from whole thickness of 1.9 cm. while the other horn was free of tumor tissue. The microscopic examination of the uterus revealed G2 endometrioid adenocarcinoma of the endometrium of the greater horn with infiltration of more than 50% of the myometrium. In the presence of bicornuate uterus, a bilateral endometrial biopsy should be performed in order to reduce the risk of delayed or missed diagnosis. The management of a case of bicornuate unicollis uterus with endometrial carcinoma in only one horn is the same as patients with endometrial cancer in single uterus and depends mainly on stage and histological grade of the tumor. The possibility of existence of a separate uterine cavity should always be considered when endometrial cancer is clinically suspected but pathology fails to confirm the diagnosis. This points out the importance of a careful physical examination and radiographic evaluation in such cases.
