Peritoneal inclusion cyst is a relatively uncommon benign pathology of the peritoneum.[1]
It is also known as benign multicystic mesothelioma; it should not be confused with malignant mesothelioma and benign papillary mesothelioma.
It may referred to as inflammatory cyst of the peritoneum or mesothelial inclusion cyst.[citation needed]
