Hemangioma is a tumor or vascular malformation that occurs in vascular tissue, 80% of which are congenital, benign, slow-growing, and rarely malignant. Hemangiomas that occur in the oral and maxillofacial regions account for 60% of all hemangiomas in the body, most of which occur in facial skin, subcutaneous tissue, and oral mucosa, such as the tongue, lips, and floor of the mouth, and a few occur in the jawbone or deep tissue. Hemangiomas are more common in infants at birth or shortly after birth. They originate from residual embryonic angioblasts. Active endothelial-like germs invade adjacent tissues to form endothelial-like cords, which are connected to the remaining blood vessels after tubulation to form hemangiomas. The blood vessels in the tumor form their own system and are not connected to the surrounding blood vessels.
