title: [Ovarian mucinous adenocarcinoma, mucocele of the appendix and pseudomyxoma peritonei: case report with immunohistochemical analysis].
abstract: Women with pseudomyxoma peritonei may have both, appendiceal and ovarian mucinous tumors, and there is a considerable debate regarding the site of origin of the tumor in such cases. Recent studies which have investigated the histological and immunohistochemical profile of these tumors showed, that ovarian tumors in most cases are secondary to the appendiceal tumors. In our case report we demonstrate that, despite of extensive immunohistochemical examinations (analysis of CK 7, 18, 20, CEA, HAM 56), it may be difficult to determine the histogenetic origin of pseudomyxoma peritonei.
