Abstract

Parovarian tumors may be of mesothelial, mesonephric (Wolffian), or paramesonephric (Mullerian) origin. An estimated 10% of adnexal masses are parovarian cysts, most commonly mesothelial or paramesonephric in origin. Benign neoplasms such as cystadenomas may occasionally develop in parovarian cysts. Malignancy has been reported in 2.0% to 2.8% of parovarian cystic masses, but it seems to be even less frequent in masses smaller than 5 cm. The histologic appearance of the tumor is identical with that of tumors of ovarian origin. However, their similarity of biologic behavior is uncertain. The appropriate therapy for this unusual lesion has not been fully defined, since a minimal amount of follow-up data is available on the few cases which have been reported. We had experienced a case of papillary serous cystadenocarcinoma of borderline malignancy arising from a parovarian paramesonephric cyst and report this case with a brief review of literature.
