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, mostly appendiceal tumor has been implicated as the primary cause of pseudomyxoma peritonei.
- Studies have shown and supported the fact 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.
- 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, other conditions may also be found, including disseminated peritoneal adenomucinosis (DPAM), peritoneal carcinomas, or several mucinous tumors (mucinous adenocarcinoma, mucinous cystadenoma, and mucinous cystadenocarcinoma).[2]
