A case of Endometrioid endometrial adenocarcinoma with synchronous low-grade Appendiceal mucinous neoplasm and Pseudomyxoma peritonei.

Pseudomyxoma peritonei (PMP) is a rare condition usually associated with ruptured low-grade mucinous neoplasm of the appendix. Rarely, PMP can originate from mucinous adenocarcinoma of the ovary. However, the coexistence of adenocarcinoma of the endometrium and appendiceal mucinous neoplasm has not been reported.
