Kasabach–Merritt syndrome (KMS), also known as Hemangioma with thrombocytopenia, is a rare disease, usually of infants, in which a vascular tumor leads to decreased platelet counts and sometimes other bleeding problems, which can be life-threatening. It is also known as hemangioma thrombocytopenia syndrome.

When these tumors are large or are growing rapidly, sometimes they can trap platelets, causing severe thrombocytopenia. The combination of vascular tumor and consumptive thrombocytopenia defines KMS. Tumors can be found in the trunk, upper and lower extremities, retroperitoneum, and in the cervical and facial areas.

surgical resection of vascular tumors
Embolization (by interventional radiology) can limit the tumor's blood supply
External compression bandages can have similar effects
#certain medications, including:

* corticosteroids
* alpha-interferon
* chemotherapy (e.g. vincristine)
