The ultrastructural features of a sclerosing hemangioma of the lung in a 34 year old woman are described. The basic cellular response is thought to be endothelial and not epithelial. These conclusions are based on the finding of Weibel-Palade bodies within the tumor cells in addition to other characteristics generally associated with endothelial cells.
