Benign peritoneal mesothelioma. Histopathology in a case.
A case of peritoneal mesothelioma was histopathologically diagnosed in a 40-year-old woman. Localized solitary firm nodules found in omentum appeared microscopically as trabecular proliferations with a plexiform pattern in a myxoid stroma. The tumors were penetrated by clefts and cystic cavities lined by a cuboidal or endotheliform epithelium. Rare psammoma bodies were present. The stroma was rich in hyaluronic acid and slightly positive for neutral mucopolysaccharides.
