[Blue rubber bleb naevus syndrome involving the pleura]

Bean's syndrome ('blue rubber bleb nevus syndrome') is a rare disease characterized by venous malformations involving various organs. Most often these lesions are localized to the skin and the digestive system. Gastro-intestinal bleeding is the most frequent presentation. Though other organs can be affected, chest localizations are infrequent and pleural localization is exceptional. We report the case of an asbestos-exposed patient with Bean's syndrome with characteristic skin lesions, smoker, hospitalized for the investigation of a hemorrhagic pleural effusion. A medical thoracoscopy revealed pleural lesions similar to the cutaneous lesions and compatible with a pleural localization of the disease. This is the first documented case of this disease involving the pleura. A review of the literature was carried out on account of this clinical case.
