Sirolimus for treatment of Kaposiform hemangioendothelioma with Kasabach-Merritt phenomenon: A retrospective cohort study

Abstract

Kaposiform hemangioendothelima (KHE) is a locally aggressive vascular tumor that mainly occurs during childhood and invades adjacent tissue and organ. It is commonly complicated by Kasabach-Merritt phenomenon (KMP) in about 50%-70% of the cases. KMP is most often associated with a rapidly growing, large solitary tumor that may result in severe hemorrhage and directly responsible for high mortality and morbidity.
