[Sclerosing hemangioma of the lung: a rare lesion with a difficult diagnosis]. / L'hémangiome sclérosant du poumon: une lésion rare et de diagnostic difficile.

Sclerosing hemangioma of the lung is a rare lesion described for the first time in 1956 by Liebow. We report a case in a 45 year-old woman who was admitted for exploration of chronic cough. The chest x-ray revealed a round opacity, well delimited in the left pulmonary parenchyma. Surgical resection enabled the histopathological diagnosis of sclerosing hemangioma. We review progress in our knowledge of the histogenesis and diagnosis of this tumor. Immunohistochemistry has been highly contributory although numerous points remain controversial.
