Early postnatal proliferation of rapidly involuting congenital hemangioma.

Congenital hemangiomas (CH) are benign vascular tumors characterized by being fully developed at birth and following a variable postnatal course. We present the case of a newborn with a CH who experienced proliferation before developing an ulceration followed by rapid involution. This case expands the clinical spectrum of CH, highlighting the variable course of this vascular tumor.
