Two Cases of Congenital Hemangioma / 대한피부과학회지

ABSTRACT

Congenital hemangioma (CH) is a fully formed benign vascular tumor at the time of birth and do not proliferate in postnatal life. CH must be differentiated from infantile hemangioma. CH has three subtypes that are recognized based on their natural history: Rapidly involuting congenital hemangioma (RICH), non-involuting congenital hemangioma (NICH), and partially involuting congenital hemangioma (PICH). It is important to distinguish RICH from NICH because RICH spontaneously regresses but NICH does not. Herein, we report two patients diagnosed with RICH and NICH, respectively. We presented the clinical features as well as ultrasonographic and histologic findings to distinguish congenital from infantile hemangioma.
