Paravaginal wolffian duct (mesonephros) adenocarcinoma: a light and electron microscopic study.
This is a report of an adenocarcinoma of mesonephric origin studied by light microscopy, electron microscopy, and immunocytochemistry. Unlike previous reports, our lesion was located paravaginally and not in the leaves of the broad ligament or in the cervix. The light microscopic features are similar to those of previous cases in the literature. Although not specific, the ultrastructural features of the tumor are similar to those of mesonephric structures and different from those of müllerian structures. The diagnosis always should be considered when a tumor occurs at the site where mesonephric remnants may be found and after exclusion of a carcinoma of other pelvic organs or a metastasis from a primary neoplasm elsewhere.
