Successful combination therapy of propranolol and prednisolone for a case with congenital Kasabach-Merritt syndrome.

A male fetus was delivered by cesarean section with a large hemangioma on his right chest and thrombocytopenia. Clinically, Kasabach-Merritt syndrome (KMS) was suspected, and immediately he was treated with daily prednisolone (PSL) 1 mg/kg and recombinant thrombomodulin without response. Additional propranolol (1-3 mg/kg per day) and increased PSL 2 mg/kg per day therapy successfully controlled his disseminated intravascular coagulation and decreased the tumor size without serious side-effects. No relapse of KMS was observed after cease of PSL and propranolol. Combined use of propranolol and corticosteroid is expected as a candidate therapeutic tool for KMS.
