Overview
Pseudomyxoma peritonei is caused by a pre-existing intraperitoneal mucinous neoplasm. The K-Ras and p53 genes may be involved in the oncogenesis.
Causes
- Studies have shown and supported that pseudomyxoma peritonei arises from primary appendiceal neoplasm rather than ovarian or colon origin.[1]
- The primary tumor appears to arise from the MUC2 expressing goblet cells and most commonly from these cells in the appendix. [2]
- The K-Ras and p53 genes may be involved in the oncogenesis.
- While the majority of pseudomyxoma peritonei are associated with appendiceal carcinomas, other conditions may also be found, including disseminated peritoneal adenomucinosis (DPAM), peritoneal carcinomas, or several mucinous tumors (mucinous adenocarcinoma, mucinous cystadenoma, and mucinous cystadenocarcinoma).[3]
