Kasabach-Merritt syndrome is a rare but life-threatening disease in which a rapidly growing vascular tumor induces localized intravascular coagulation, causing thrombocytopenia, microangiopathic hemolytic anemia, and consumption coagulopathy. It presents mainly in infants and young children. We present an adult with recurrent and severe lower gastrointestinal bleeding due to Kasabach-Merritt syndrome, treated successfully with sirolimus after multiple other failed interventions.
