What are the clinical features of infantile hemangioma?

Infantile hemangiomas are soft, round, hemispherical, lobulated, or irregularly raised tumors of varying sizes, from the size of a grain of rice to a strawberry, and sometimes covering the entire limb. The lesions are bright red or dark red, with clear, soft edges, and may fade when pressed. The lesion area forms bright red macules and papule-like masses. Early symptoms may not be typical, but may appear as abrasion-like skin or vasodilated patches, or even as hypopigmented patches. With the extension of time can gradually develop into typical damage. Superficial infantile hemangioma may develop into limited bright red raised plaques or nodules, which are dome shaped and resemble rubber when touched, and the color partially fades when pressed. 2.Deep infantile hemangioma may appear as red or dark purple skin lumps, which shrink in size after squeezing, but swell and deepen in color when pressing and crying. 3.Mixed type hemangioma is a deep soft mass and a central superficial hemangioma-like lesion. Infantile hemangiomas often occur on the face, neck, scalp, shoulders or trunk extremities, with a few involving the mucous membranes. Most patients have only a single lesion, but a few have multiple lesions. Most of them develop within 1-3 months after birth, and the damage grows rapidly within 3-6 months after birth and 6-12 months after birth. The damage grows slowly within 3-6 months and 6-12 months after birth, and may recede spontaneously within a few years, or may rupture and bleed or become infected, with scar healing occurring later. Thrombocytopenia complicated by hemangioma syndrome may occur in very few children. The disease can also occur in childhood and adulthood, and develops slowly, ceasing to enlarge after a certain point and often never disappearing.
