Kasabach–Merritt syndrome

Kasabach–Merritt (KMS), also known as hemangioma with thrombocytopenia, is a rare disease, usually of infants, in which a tumor leads to decreased platelet counts and sometimes other bleeding problems, which can be life-threatening. It is also known as hemangioma thrombocytopenia syndrome. It is named after Haig Haigouni Kasabach and Katharine Krom Merritt, the two pediatricians who first described the condition in 1940.
