It is a benign tumor of congenital capillary hyperplasia and dilatation, mostly occurring at birth or shortly after birth. Rarely, it begins in childhood or adulthood. It increases in size with age and stops developing in adulthood. Most of them invade the skin of head and neck, but they can also occur in mucous membranes, liver, legs and muscles. It grows rapidly in infancy and then gradually stops growing and sometimes regresses on its own. The tumor can cause some comorbidities during the growth process, such as bleeding or ulceration, arteriovenous fistula and thrombocytopenia in case of trauma or infection. Clinically, there are four types of nevus, simple hemangioma, spongy and mixed hemangioma. Erythema nevus: Also known as capillary nevus or wine-like nevus, it is multiple and often occurs shortly after birth. It is mostly seen on the occipital and forehead side of the face, mostly unilateral, occasionally bilateral, and generally does not exceed the midline. It grows rapidly in infancy and develops slowly afterwards, and stops expanding after reaching a certain level. The lesions vary in size and are light red or purplish-red spots that fade when pressed. Simple hemangioma: Also known as capillary hemangioma or straw frosty tumor, it appears as one or several bright red hemispherical soft and lobulated tumors, mostly appearing at birth or 3-5 weeks after birth, with fast growth rate, growing to the maximum in part within 1 year of age, and may subside. Most of them regress within 5-7 years. Capillary hemangioma is composed of a large number of intertwined and dilated capillaries, mostly found in the facial skin, bright red or purplish red, level with the skin surface, clearly circumscribed, irregular in shape and varying in size, from small spots to several centimeters. When the tumor is pressed by finger, the surface color will recede, and when the pressure is released, the blood will immediately fill the tumor and the tumor will regain its original size and color, and this type of large area is called wine spot hemangioma. Another type of hemangioma is prune-like hemangioma, which protrudes from the skin and resembles prune-like with uneven height. Spongiotic hemangioma: It usually occurs in the subcutaneous and submucous membranes, and can reach deep into the muscular layer, mostly occurs at birth or soon after birth, usually on the head and face. Mixed type: It consists of two types of hemangioma existing at the same time, but one type is predominant.
