Vincristine-ticlopidine-aspirin: an effective therapy in children with Kasabach-Merritt phenomenon associated with vascular tumors.

ABSTRACT

Kasabach-Merritt phenomenon (KMP) is a serious coagulopathy with severe thrombocytopenia (<10,000/mm³) that occurs in the presence of an enlarging vascular tumor such as kaposiform hemangioendothelioma (KHE) and tufted angioma (TA). The natural history and treatment of these lesions remain controversial. The authors report a KHE case and a TA case that presented with KMP, describing their successful pharmacological management with vincristine, ticlopidine, and aspirin.
