This tumor, which manifests as small red or purple patches on the skin of the neck and upper trunk, grow slowly and, in some individuals, can ultimately cover large areas of the upper trunk and neck. Tufted angioma is very similar to kaposiform hemangioendothelioma (KHE). So-called "acquired" tufted angioma appears in childhood as a localized, hard, dull red or purple patch of several centimeters in size. A large tufted angioma can be associated with platelet trapping.
