What is benign multicystic peritoneal mesothelioma?

Benign multicystic peritoneal mesothelioma (BMPM) is a very rare benign cystic tumor arising from the peritoneal mesothelium (lining of the abdominal wall). It commonly occurs in young to middle-aged women who have a prior history of abdominal surgery, endometriosis, or pelvic inflammatory disease. The first symptoms usually include abdominal or pelvic pain, tenderness, and rarely, constipation and/or urinary hesitancy. Since it was first described in 1979, there have been approximately 130 cases described in the medical literature. BMPM is not related to prior asbestos exposure. The specific cause is unknown.[1][2]

How might benign multicystic peritoneal mesothelioma be treated?

Surgery to remove the cystic lesions is the only effective treatment for BMPM. Aggressive surgical approaches are often recommended. Hormonal therapy has also been attempted in individual cases with variable degrees of success. Most affected individuals do not undergo chemotherapy and/or radiotherapy because these tumors are usually benign.[1][2]

What is the prognosis for benign multicystic peritoneal mesothelioma?

Most people do well after surgery to remove the cysts. However, about 50 percent of patients experience a recurrence one to 27 years after their initial diagnosis. These cysts rarely become a malignant (cancerous). However, routine follow-up imaging is necessary after abdominal surgery in all patients because of the risk of recurrence.[1][2]
