Mesothelium and malignant mesothelioma of the pericardium

: Malignant mesothelioma of the pericardium is characterized by atypical solid growth of mesothelium with formation of atypical cavities, slits surrounded by a fibrous stroma. Unless early biopsy, diagnosis and surgery, the prognosis is unfavourable. It is desirable to create immunomorphological test for mesothelium. Recognition of epithelioid, fibrous and mixed forms of mesotheliomas is disputable.
