Desmoplastic malignant mesothelioma of the pericardium: Description of a case and review of the literature.

Desmoplastic mesothelioma (DMM) is a rare and highly lethal subtype of diffuse malignant mesothelioma and is often difficult to distinguish from reactive pleural fibrosis. The term "desmoplastic" refers to the growth of fibrous or connective tissue. We report the clinical, radiological, and pathological features of a primary DMM of the pericardium and a short review of the literature. A 72-year-old man was admitted presenting shortness of breath, cough, and asthenia. Computed tomography scan showed thickenings and effusions both in the pleura and in the pericardium. Histopathological diagnosis was performed by surgical pericardial biopsy and confirmed by autopsy. The patient had a history of asbestos exposure. Primary mesothelioma of the pericardium is a rare tumor occurring in the fourth to seventh decades with nonspecific symptoms and a rapid clinical course. The diagnosis is difficult and often needing a surgical pericardial biopsy. The prognosis is poor although newer antiblastic drugs seem to prolong survival times.
