Bilateral ovarian cysts with squamous intraepithelial neoplasia.

Summary We report a case of bilateral ovarian cysts lined exclusively by squamous epithelium showing multifocal intraepithelial neoplasia. The cervix showed synchronous high-grade intraepithelial neoplasia (CIN III). We interpreted the ovarian lesions as squamous carcinoma of borderline malignancy and believe that they are part of a “field change” that also involves the cervix.
