Kasabach–Merritt Syndrome is a rare, life-threatening vascular disorder that typically affects infants. It is characterized by a rapidly growing, large blood vessel tumor (hemangioma) that traps platelets, causing severe bleeding problems.
read more about kasabachmerritt syndrome ...The cause is the formation of a large, abnormal vascular tumor in infancy. This tumor acts like a sponge, trapping a vast number of platelets inside its structure. Since platelets are necessary for clotting, their sequestration leads to a severe drop in the circulating platelet count, causing dangerous, spontaneous internal bleeding.
Symptoms define a severe bleeding disorder. These include rapid growth of a large, discolored tumor (usually red or purple) and signs of widespread bleeding, such as petechiae (tiny red spots under the skin), easy bruising, and internal hemorrhage.
Kasabach?Merritt Syndrome can severely impact eye health if the vascular tumor forms in the orbit or on the eyelid. The rapidly growing mass can push the eyeball outward (proptosis) or cause bleeding and swelling, severely threatening vision. The associated low platelet count increases the risk of retinal hemorrhages.
Diagnosis involves confirming the low platelet count and the presence of the vascular tumor. Blood tests confirm the severe thrombocytopenia (low platelets). Imaging tests (ultrasound or MRI) are used to assess the tumor's size and blood supply.
Necessary treatments focus on controlling bleeding and shrinking the tumor. Medications, often high-dose corticosteroids or targeted chemotherapy, are used to stop the tumor growth and release the trapped platelets. Blood transfusions may be needed during severe bleeding crises.
No, the tumor is benign (non-cancerous), but its rapid growth and severe consumption of platelets make it life-threatening.
Yes, if the tumor is shrunk and the platelet count normalizes, the life-threatening condition is resolved.
Treatment with medication is often successful at shrinking the tumor and reversing the syndrome.
Seek immediate hematological care for a rapidly enlarging purple birthmark accompanied by easy bruising or nosebleeds. This syndrome involves "Platelet Sequestration" within a vascular tumor. A doctor must monitor for "Retinal Hemorrhages" which can occur if the platelet count drops dangerously low.
