Endometrial carcinoma with choriocarcinomatous differentiation: a case report and review of the literature

Abstract

Background: Choriocarcinomas unrelated to pregnancy, teratomas, or germ cell tumors have been found in the stomach, lungs, colon, esophagus, bladder, breast, renal pelvis and other sites.

Case: We present a case of a 58-year-old woman with endometrial carcinoma with choriocarcinomatous differentiation. She received surgery and chemotherapy for endometrial adenocarcinoma. However, a metastatic tumor of choriocarcinomatous element appeared at the vaginal cuff 9 months after surgery. Additional chemotherapy for choriocarcinoma resulted in a decrease in the serum hCG and the tumor regressed. Fifty months following surgery, she is alive without disease.

Conclusion: Treatment and follow-up must be performed not only for the adenocarcinoma element but also for the choriocarcinoma element in patients presenting with endometrial carcinoma with choriocarcinomatous differentiation.
