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.
PHACES association is the name given to a collection of features that are often seen together. This page from Great Ormond Street Hospital (GOSH) provides information about the medical condition PHACES association (previously referred to as PHACES syndrome) and what to expect when a child comes to GOSH for assessment and treatment.
