Sclerosing hemangioma of the lung: a clinicopathologic study of 51 cases

Abstract

The clinical and pathologic features of 51 sclerosing hemangiomas of the lung are reviewed. This tumor is benign and occurs predominantly in women. It has a variegated histologic appearance characterized by an admixture of four major histologic patterns: solid, hemorrhagic, papillary, and sclerotic. Characteristic uniform round cells are found within the stroma in all patterns and are unique to this tumor. Sclerosing hemangioma is a distinct clinicopathologic entity and should be distinguished from other benign neoplasms or inflammatory lesions of the lung.
