Kasabach–Merritt syndrome (1940)
Also known as Kasabach-Merritt Phenomenon.
Kasabach Merritt syndrome is a life threatening thrombocytopenia coagulopathy associated with specific aggressive vascular tumours. It was first described by Katharine Krom Merritt (1886–1986) and Haig Haigouni Kasabach (1898–1943), who reported a case of thrombopenic purpura associated with benign hemangioma in an infant seen at the Columbia University Babies Hospital in 1940.
Kasabach-Merritt syndrome appears to result from platelet trapping within the tumour secondary to platelet activation and fibrinogen consumption. This, in turn leads to intra-lesional bleeding and hemangioma enlargement. It is associated with high mortality rate, associated with degree of coagulopathy.
Thrombopenic purpura associated with benign hemangioma is rare. In fact, we have not been able to find a record of a combination of these two conditions in the medical literature. We wish to report the following case of an extensive hemangioma of the skin associated with diffuse purpuric manifestations.Kasabach, Merritt. 1940
