Rapidly involuting congenital hemangiomas (RICH) are a distinctive type of congenital hemangioma that are fully formed in utero and differ from non-involuting congenital haemangiomas (NICH) mainly because they undergo rapid postnatal involution.
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). 13 total HPO annotations.
