Among them, diffuse malignant mesothelioma is one of the worst prognosis tumors in the chest. Most patients are between the ages of 40 and 70, with more men than women. 2. Peritoneal mesothelioma is a tumor that originates from peritoneal mesothelial cells. The clinical manifestations are not characteristic. Common symptoms and signs are: abdominal pain, ascites, bloating, and abdominal mass. Peritoneal mesothelioma accounts for about 20% of all mesothelioma cases and can occur at the age of 2-92 years, with an average age of 54 years, of which about 63% of cases are between 45-64 years, and children are rare.
