9 years of age Greater than 50% will leave cutaneous sequelae after involution Unlike infantile hemangiomas, congenital hemangiomas are present at birth and may either rapidly involute over 18 months or persist throughout life Infantile hemangiomas can be subdivided into three types as follows: Superficial hemangiomas are confined to the upper dermis Formerly called capillary or strawberry hemangiomas , these lesions are red, raised, well demarcated, and compressible ( Fig 120.16 ) Deep hemangiomas lie in the lower dermis or subcutaneous fat Formerly called cavernous hemangiomas, these tend to have indistinct margins, and the overlying skin often has a bluish hue ( Fig 120.17 ) On close inspection, many hemangiomas have a combination of both superficial and deep elements, and thus are called mixed hemangiomas FIGURE 120.16 Superficial hemangioma of hand (Reprinted with permission from O’Doherty N Atlas of the Newborn Philadelphia, PA: JB Lippincott; 1979.)
