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
- Since initial descriptions of pseudomyxoma peritonei as a syndrome in association with an ovarian tumor or an appendiceal mucocele, a pre-existing intraperitoneal mucinous neoplasm has been implicated as the primary cause of pseudomyxoma peritonei.
- Emerging evidence supports the appendiceal rather than ovarian origin of the disease.[1]
- The primary tumor appears to arise from the MUC2 expressing goblet cells and most commonly from these cells in the appendix.
- The K-Ras and p53 genes may be involved in the oncogenesis. It may be diagnosed with a range of conditions.
- While the majority of pseudomyxoma peritonei are associated with appendiceal carcinomas,[2] 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]
