Co-occurrence of different tumor types in a same patient’s ovaries diagnosed with endometriosis is a rare phenomenon.


In this article we present an uncommon association of three distinct ovarian pathologies in a same woman presenting with adnexal mass. A 31-year-old nulliparous woman with a large persistent adnexal mass underwent laparoscopic surgery. Imaging demonstrated a multi-cystic mass with internal echoes. Tumor markers were within normal range. Based on histopathologic assessment, benign mucinous cystadenoma and mature cystic teratoma of the right ovary together with endometrioma of left ovary were revealed.


In cases of large adnexal mass, the of existence of more than one tumor type and the involvement of the contralateral ovary is possible. Also, the possibility of concurrent underlying malignancy or diminished ovarian reserve should be kept in mind.

Keywords: Endometriosis, Ovary, Teratoma, Mucinous cystadenoma, Laparoscopy, Case report

Core tip: Existence of three distinct tumor types in the ovary is a rare phenomenon. This manuscript presents scarce association of endometrioma with teratoma and mucinous cystadenoma which was confirmed by histologic assessment.
