title: [Well-differentiated papillary mesothelioma--a rare neoplasm of the peritoneum].
abstract: Well differentiated papillary mesothelioma (WDPM) is a very uncommon neoplasm of peritoneum. Most frequently it appears like little numerous nodules on peritoneal surface, omentum or mesentery. WDPM is characterized by indolent course and is diagnosed in most cases incidentally during operations for other reasons. Sometimes differentiation between WDPM and other mesothelial lesions may be difficult. In the described case a 22 year old female, cystic peritoneal lesions were first recognized histological as WDPM. In verification after two months, they were proved to be cystic mesotheliosis. WDPM may cause adhesions followed by torsion or strangulation. In the second reported case a 24 year old male, WDPM provokes torsion of the omentum. Twelve months after operation and diagnosis this patient is symptom free.
