Metastatic Female Adnexal Tumor of Probable Wolffian Origin

Abstract Female adnexal tumor of probable wolffian origin is a rare neoplasm that can present diagnostic difficulties. We report herein a case of a 60-year-old woman with female adnexal tumor of probable wolffian origin arising within the leaves of a broad ligament and, 5 years later, presenting with metastasis to the liver. The morphologic, immunohistochemical, ultrastructural, and DNA ploidy findings of the original and metastatic tumor, differential diagnoses, and the results of the English-language literature review are presented.
