Kasabach–Merritt syndrome (KMS) is a potentially life-threatening coagulopathy characterized by enlarging hemangioma with severe thrombocytopenia.[1] KMS. Kasabach-Merritt syndrome is characterised by the combination of rapidly growing vascular tumour, thrombocytopenia, microangiopathic haemolytic anaemia. [2] Thereafter, the association of a capillary hemangioma and thrombocytopenia was labeled Kasabach-Merritt syndrome (the name was later changed to KMP).

No history of neonatal problems. While the patient was in hospital she was seen again by the ENT surgeon who assured the parents. Views Read Edit View history. The cardinal clinical and hematological features of this syndrome include an enlarging infantile vascular lesion, profound thrombocytopenia, a microangiopathic hemolytic anemia, and consumptive kasabacb.

Symptoms of the following disorders can be similar to those of Kasabach-Merritt phenomenon. The possibility sydnrome disseminated intravascular coagulationa dangerous and difficult-to-manage condition, is concerning.

A case report and review of literature. Nil Conflict of Interest: When these tumors with KMP are internal such as in the pleural or retroperitoneum, they can cause significant morbidity and mortality. Comparisons may be useful for a differential diagnosis:. Megritt The cause of Kasabach-Merritt phenomenon is unknown. This consumptive coagulopathy also uses up clotting factorssuch as fibrinogen which may worsen bleeding. These synsrome occur in the extremities, chest, neck, abdomen and pelvis.


A clinical diagnosis of hemangioma involving the right parotid extending on to the right temporal area was made. Report of a case. Historically, the first-line of treatment has been high-dose systemic corticosteroids.

N Engl J Med. Bone marrow, following aspiration, was normocellular with only megakaryocytic hyperplasia which suggested Idiopathic thrombocytopenic purpura. Vascular Malformations Large malformations synrome as venous or venous lymphatic lesions and multiple lesions can causes coagulopathies with low platelet counts and other coagulation proteins. Treatment is administered at standard doses 1—1. Treatment was started with compression bandage and steroids. Corticosteroids have been the traditional first-line therapy for KMS when surgical mmerritt is not possible.

Neonatal Kasabach-Merritt phenomenon

Sustained hypoglycemia in infancy kasxbach been associated with long-term neurologic sequelae. Treatment of Kasabach—Merritt syndrome: Treatment of childhood kaposiform hemangioendothelioma with sirolimus. Kasabach-Merritt syndrome is characterised by the combination of rapidly growing vascular tumour, thrombocytopenia, microangiopathic haemolytic anaemia and consumptive coagulopathy. Steroids tapered gradually over 2 weeks and slow vincristine tapering was planned over the next months.

Parents refused biopsy and injection Vincristine was started at a dose of 0.

Kasabach-Merritt syndrome

Propranolol was tapered after a month and steroids were continued and then tapered. It usually presents in early infancy, but onset in early neonatal period, facial hemangioma, and vincristine use in neonates has rarely been reported.

A stepwise regimen of prednisolone, dipyridamole, and interferon. D ICD – Enjolras and associates have reported that several steroid non-responders show dramatic response to vincristine. The association of hemangioma, thrombocytopenia, and hypofibrinogenemia was first described in by Kasabach and Merritt [ 1 ], who took care of an infant with a giant capillary hemangioma and thrombocytopenic purpura.

National Center for Biotechnology InformationU. Most experiences with propranolol are in very different clinical contexts — sick infants, closely monitored and in hospital drug initiation. It interferes with the mitotic spindle microtubules by binding to tubulin, resulting in inhibition of mitosis. Successful treatment of kasabach-Merritt syndrome with vincristine and surgery: All subjects with KMP had profound thrombocytopenia and hypofibrinogenemia with elevated fibrin split products D-dimerssuggestive of an active consumptive coagulopathy.

The hemangioma is often within the skin but can be present anywhere, including retroperitoneal organs, the mediastinum, the pelvis, visceral organs, or the mesentery.

Peripheral smear revealed features of hemolysis with severe thrombocytopenia. Andrews’ Diseases of the Skin: Ravi Kumar1 and Divya Swathi.
