Non-involuting congenital hemangioma (NICH) is a rare type of infantile hemangioma, which is a tumor that forms from the abnormal growth of blood vessels in the skin. NICH looks like an oval,purplish mark or bump that can occur on any part of the body. NICH is present from birth (congenital) and increases in size as the child grows. Unlike other hemangiomas, NICH do not disappear spontaneously (involute).
Features include always present findings: Hemangioma; and common findings: Midfrontal capillary hemangioma, Subcutaneous calcification, Perineal hemangioma, and Visible small blood vessels on skin (telangiectasia of the skin). 11 total HPO annotations.
