Abstract:
Various etiologies of spontaneous hemothorax have been reported, though the cause remains unidentified in some patients despite an exploratory thoracotomy. We report on an 89-year-old man with spontaneous hemothorax resolved by partial resection of the lung using complete video-assisted thoracoscopic surgery. The histopathologic findings revealed a ruptured micro-venous hemangioma located just below the bleeding visceral pleura. To the best of our knowledge, this is the first report of spontaneous hemothorax caused by a pulmonary micro-venous hemangioma.
