So-called sclerosing hemangioma of the lung

Abstract

Sclerosing hemangiomas of the lung are benign neoplasms of uncertain histogenesis. We utilized histochemistry in five cases, immunohistochemistry in six, electron microscopy in seven, and glycosaminoglycan electrophoresis in three to elucidate better the origin of this tumor. The evidence accrued from these studies suggests that the pulmonary sclerosing hemangioma represents a form of benign epithelial mesothelioma.
