Mesonephric (Wolffian) Pseudoendometrioid Carcinoma of the Broad Ligament, Arising From a Papillary Cystadenoma

This article describes the case of a 70-year-old woman with an adnexal cystadenocarcinoma located in the right broad ligament and displaying a striking resemblance to a well-differentiated endometrioid adenocarcinoma. The uniqueness of this pseudoendometrioid carcinoma lies in the fact that its mesonephric nature is revealed by the origin from a papillary cystadenoma of the broad ligament, where remnants of the mesonephric duct are seated, and the immunohistochemical profile, particularly a uniform negativity for estrogen and progesterone receptors, apical-luminal positivity for CD10, and strong nuclear positivity for GATA3.
