Abstract

The association of a pseudomyxoma peritonei with a mucinous tumor of the appendix and/or the ovary is regularly reported in the literature. However, in this context, endometrial or endocervical lesions remain exceptional. We report the case of a 57-year-old patient, with pseudomyxoma peritonei associated with a low-grade mucinous neoplasia of appendix and both ovaries. The systematic sampling of endometrium and endocervix showed small segments of intestinal epithelium admixed with native epithelium. Histological and immunohistochemical characteristics of this epithelium were quite comparable to those observed in the appendix and ovaries. The endocervical and endometrial lesions might represent an implantation of mucinous epithelium from appendix, emphasizing the capacity of this epithelium to implant at a distance from the original lesion.
