We report a case of thrombocytopenia caused by Kasabach-Merritt syndrome (KMS) in a 69-year-old man with a metastatic angiosarcoma of the scalp. A review of the literature revealed that only 4 cases of KMS associated with angiosarcoma have been previously reported. All these cases occurred with a solitary large lesion. This is the first case of thrombocytopenia caused by KMS associated with small metastatic lesions of angiosarcoma that developed after the primary lesion has been completely removed.
