Abstract
Background: Enterobiasis occurs throughout the female genital tract and may involve peritoneal surfaces. It is generally an incidental finding at surgery or at autopsy but occasionally is symptomatic. Most of the superficial lesions are composed of granulomas with variable fibrosis in which diagnostic eggs are found, often associated with degenerated adult worms. Multiple histologic sections may be required to establish the diagnosis in older lesions.Case: A case of enterobiasis of the ovary in a patient with squamous-cell carcinoma in situ of the cervix is presented. The features of enterobiasis are discussed.Conclusion: The importance of mistaking such lesions for ovarian cancer is discussed.
