Background: Infantile hemangiomas are benign vascular neoplasms
that have a characteristic clinical course marked by early proliferation
and followed by spontaneous involution. During the proliferative phase in
the neonatal period or early infancy, a rapidly dividing endothelial cell
proliferation is responsible for the enlargement of these lesions. Finally,
an involutional phase occurs, whereby most hemangiomas are clinically resolved
by age 9 years. Hemangiomas are the most common tumors of infancy, and most
are medically insignificant. Occasionally, hemangiomas may impinge on vital
structures, ulcerate, bleed, or cause high-output cardiac failure or significant
structural abnormalities. Rarely, a cutaneous hemangioma is associated with
one or more underlying congenital anomalies. |
