A case report of mucinous cystadenoma with contralateral serous cystadenofibroma in identical twin

초록

Introduction: There are limited reports on ovarian neoplasm occurring among identical twins. Most previous reports showed ovarian teratoma found in both twins. Herein, we report for the first time a case of ovarian mucinous cystadenoma with contralateral serous cystadenofibroma found in twin siblings. Case report: One patient suffered from abdominal distension and the following computed tomography found ovarian mucinous cystadenoma. During the laparoscopy, another ovarian mass was found in the contralateral ovary. The histopathology revealed ovarian mucinous cystadenoma with contralateral serous cystadenofibroma. The twin sister had no symptoms but underwent gynecological screening. She also showed a similar finding, mucinous cystadenoma with serous cystadenofibroma on the contralateral ovary. Both patients underwent laparoscopic bilateral ovarian cystectomy. Conclusion: This is the first clinical report on left ovarian mucinous cystadenoma with right serous cystadenofibroma in twin siblings. Our cases support awareness of ovarian tumors in twin sisters.
