[Pleural fibrous mesothelioma. Apropos of a case]

A 27-year-old man with an uneventful history was hospitalized after fortuitous discovery of an opacity in the right lung field. The clinical examination revealed a multi-nodular euthyroidian goiter. Laboratory tests, including blood glucose, were normal. Computed tomography of the chest showed a pleural formation and associated pleural effusion. Complete surgical exeresis led to the diagnosis of benign fibrous pleural mesothelioma. Fibromas of the pleura are rare and usually discovered due to extra thoracic signs. The clinical course is long and often silent. Surgical removal is indicated and usually is complete.
