[Pleurisy and sarcoidosis. Apropos of a case].

Abstract

The authors report a case of bilateral hilar lymphoma of sarcoid origin associated with a pleural effusion. With the exception of pneumothorax, the pleural manifestations in the course of sarcoidosis amount to 115 published cases, including 49 with histopathological proof enabling us to speak of a pleural sarcoidosis. When the histopathological diagnosis is missing, it is preferable to speak of sarcoidotic pleurisy: the aetiopathogenesis in this case is venous obstruction and/or lymphatic obstruction by sarcoid involved lymph nodes. Exceptionally, it could be due to heart failure due to the fibrotic stage of sarcoidosis or to an autonomous sarcoidotic myocarditis.
