Kaposiform haemangioendothelioma 

Kaposiform haemangioendothelioma (KHE) is a rare vascular (blood vessel) growth that may involve the skin and/or internal organs. It usually appears at birth or soon afterwards and in the early stages can be confused with other types of birthmark, such as an infantile haemangioma (also known as a haemangioma of infancy). Although it may be referred to as a tumour, it is not cancerous and does not spread to other parts of the body.
