<unk>  (also known as<unk>  metastases) is defined as a malignant tumor of the peritoneum. Metastases are the most common<unk>  malignancy, commonly metastasize from ovarian cancer, colon cancer, gastric cancer, and pancreatic cancer.  Calcified<unk>  may occur in serous ovarian adenocarcinoma, colon cancer, and gastric cancer.<unk>  carcinogenesis arises from the celomic epithelium lining of the abdominal cavity (peritoneum) in response to an oncogenic stimulus. Common causes of<unk> , include:<unk>  mesothelioma, colon cancer, gastric cancer, and pancreatic cancer. Early clinical features include abdominal pain, abdominal distension, and nausea. If left untreated, the majority of patients with<unk>  may progress to develop portal hypertension, pulmonary edema, and death. Common complications of<unk>  include intestinal obstruction and pulmonary thromboembolism. The diagnosis of<unk> , include: Imaging findings compatible with<unk> , elevated protein concentration (more than 4.0 g/dL) in ascitic fluid, abnormal serum-ascites albumin gradient (less than 1.1 g/dL) in ascitic fluid, and high cell count (lymphocyte predominance). The mainstay medical therapy for<unk>  is hyperthermic intraperitoneal chemotherapy (HIPEC), followed by cytoreductive surgery, laparotomy in conjunction with cytology testing is the most common approach for the treatment of<unk> . Prognosis is generally poor, and the 5-year survival rate of patients with<unk>  is approximately 20%.
