[Histology of benign borderline ovarian and subperitoneal dystrophic cysts ]

Benign cysts of the ovary include a variety of histological types. We briefly describe here the different histological types of ovarian lesions with a cystic presentation. The cystic epithelial tumors of the ovary could be definitely benign or malignant, there also exist borderline cases which are particularly difficult to manage. Close collaboration between the surgeon and the pathologist is required to carefully define indications and the limitations of frozen-section diagnosis as well as good transfer of the operative specimen.
