General Discussion

Pseudomyxoma peritonei is a rare malignant growth characterized by the progressive accumulation of mucus-secreting (mucinous) tumor cells within the abdomen and pelvis. The disorder develops after a small growth (polyp) located within the appendix bursts through the wall of the appendix, and spreads mucus-producing tumor cells throughout the surrounding surfaces (e.g., the membrane that lines the abdominal cavity [peritoneum]). As mucinous tumor cells accumulate, the abdominal area becomes swollen and digestive (gastrointestinal) function becomes impaired. Pseudomyxoma peritonei develops at a variable rate, but may grow at a slower rate (indolent) than other malignancies within the abdomen.
