Pneumothorax and pulmonary cavitation in a man with systemic sarcoidosis.

Sarcoidosis is a multisystem granulomatous disorder with protean manifestations. Physicians should be aware of potential unusual complications and this reminds one of the paradoxical affirmation that "rare events are always possible!" The case presented demonstrates two unusual consecutive complications: pneumothorax with lobar dissociation and primary acute pulmonary cavitation. Myocardium, liver and spleen were also involved. History and evolution suggest a relationship between sarcoid activity and alcohol consumption.
