Pseudomyxoma Peritonei
Overview
Pseudomyxoma peritonei (PMP) is a rare condition that most often begins as a slow-growing mucinous tumor in the appendix, though it can occasionally originate in other parts of the abdomen such as the bowel, ovary or bladder. These tumors produce a thick, jelly-like substance called mucin. When the appendix or another affected organ ruptures, tumor cells and mucin can spread across the lining of the abdomen, the peritoneum, where they gradually build up over time.
PMP typically grows slowly and rarely spreads through the bloodstream or lymph nodes. Instead, it tends to stay within the abdominal cavity, spreading along internal surfaces and eventually putting pressure on nearby organs.
Signs & Symptoms
PMP often develops quietly, and many people have no symptoms for years. As mucin and tumor cells accumulate in the abdomen, symptoms may include:
- Gradual increase in abdominal or waist size
- Hernia or visible swelling on the abdomen
- Abdominal or pelvic discomfort
- Loss of appetite
- Unexplained weight gain
- Changes in bowel habits, such as constipation or bloating
These symptoms can be caused by many conditions, but it is important to discuss any persistent or worsening symptoms with your doctor.
Treatments & Services
Treatment Options
Treatment for pseudomyxoma peritonei depends on how extensive the disease is within the abdomen. Because PMP behaves differently from most cancers, care is often coordinated by specialists experienced in treating peritoneal surface tumors.
