Abstract

Sclerosing hemangioma of the lung is uncommon benign neoplasm of uncertain histogenesis, although their radiological appearance is relatively distinct and well-defined. Recently, we experienced 2 cases of sclerosing hemangiomas of the lungs in 61 and 39 years old women. The light microscopic findings of the tissues are similar to the features reported by Liebow and Hubbell(1956). The basic cellular response is thought to be type II pneumonocytes because of findings of multilamellar-like bodies within stromal cells with electron microscopy in case I in addition to other characteristics generally found in epithelial cells.
