Pseudomyxoma peritonei

Common Name(s)

Pseudomyxoma peritonei, Gelatinous ascites

Pseudomyxoma peritonei is a tumor that most often begins in the appendix.  As the tumor grows, tumor cells may spread into the peritoneal cavity and land on other nearby organs (such as the ovaries or intestines), sometimes forming additional tumors on the surface of these organs.   Pseudomyxoma peritonei is extremely unlikely to grow into these organs (to become invasive) or spread to more distant parts of the body (metastasize); therefore, it is not usually thought of as a malignant tumor.   It is rare, occurring in approximately two out of a million people, and women are affected two to three times more frequently than men.   The first symptoms of pseudomyxoma peritonei are an increase in the size of the belly, appendicitis, or the finding of a mass on the ovary during medical imaging tests.
