Spontaneous hemopneumothorax as a result of venous hemangioma: a unique case?

Spontaneous hemopneumothorax is a rare clinical entity that can be life-threatening, with a significant increase in mortality if not recognized and treated in time. We report the case of a young man who presented to us with nontraumatic spontaneous hemopneumothorax. Histologic examination of lung tissue showed the most likely cause of the bleeding to be venous hemangioma, which to the best of our knowledge has not been reported before.
