Pseudomyxoma peritonei is a malignant tumor that develops in the abdominal and pelvic areas. In this state tumor cells grow due to the bursting of a certain polyp with the appendix wall. When the tumor cells accumulate they make the abdominal area swollen, and the gastrointestinal functions become impaired.


Among the symptoms that indicate the development of the tumor are abdominal and pelvic pain, rapid weight change, bloating, digestive problems, and infertility.


Treatment for pseudomyxoma peritonei include intraperitoneal hyperthermic chemotherapy. In more severe cases, cytoreductive surgery can be performed to remove the peritoneum. Affected organs such as the ovaries, uterus and parts of the large intestine have be to removed as well to prevent the spread of the disease. Oral chemotherapies are also given to moderate cases.



Pseudomyxoma peritonei is usually diagnosed during surgery for certain medical problems such as hernia repair. This tumor is also associated with other appendiceal carcinomas, peritoneal carcinomas, and mucinous cancers. It can also be found via CT scan.
