Pediatric Penile Non-Involuting Congenital Hemangioma With an Associated Pyogenic Granuloma: Surgical Management of a Rare Vascular Anomaly.

By contrast, congenital hemangiomas are formed at birth and are categorized into three groups: rapidly involuting, partially-involuting, and non-involuting congenital hemangiomas (NICH).
