[A superior vena cava syndrome secondary to a pleural fibrous mesothelioma].

Benign fibrous or pleural mesothelioma are rare tumors that seem to originate in the mesenchyma (subpleural fibromas). They are usually discovered by chance and the prognosis for the patient is favorable after surgery. If the tumors are large, extrapulmonary signs may be present (hypertrophic osteoarthropathy, hypoglycemia). We describe a case of unusually large fibrous mesothelioma of the pleura that presented as superior vena cava syndrome, a complication not described in the literature.
