Surgical treatment of a primary malignant pericardial mesothelioma: case report.

Pericardial malignant mesothelioma (MM) is a rare tumour which accounts for about 1% of all mesotheliomas, 4% of the primary heart and pericardial tumours. It carries an extremely poor prognosis, with a reported overall survival of less than 6 months. Clinical symptoms and signs are frequently nonspecific, and the diagnosis is usually made after surgery or at autopsy. We report a case of a 72 years old woman with primary pericardial malignant mesothelioma involving the right atrium. Nine months following surgery, the patient is alive with good performance status.
