Fibrous Histiocytoma of the Lung (Sclerosing Hemangioma Variant?)

¹ Departments of Medicine and Pathology, The Norwalk Hospital, Norwalk, Connecticut

A case of fibrous histiocytoma (sclerosing hemangioma variant) of the lung occurring in an asymptomatic woman is presented. The clinical and histopathologic features are discussed and the literature briefly reviewed. Albeit rare, this entity enters into the differential diagnosis of any condition presenting as a "coin lesion" on the chest roentgenogram. We do not propose to reclassify all preceding reports of sclerosing hemangioma as fibrous histiocytoma because most are not. Based on a review of the literature, we believe the former term has been used to describe a variety of lesions, both vascular and inflammatory.
