[Primary peritoneal mesothelioma--report of two cases].

We report two cases of primary peritoneal mesothelioma. In both of them contact with asbestos was negative. In the first case the patient was hospitalized in another hospital five years earlier. The performed USG and CT of the abdomen revealed the tumor near the spleen. But then the patient was not operated. In the second case the symptoms lasted for several months. In both cases the tumors were nonoperative because of the advanced malignant process.
