Hemangiomas
Hemangiomas of infancy (infantile hemangiomas) represent benign vascular tumors that are present in approximately 3% of newborns and up to 10% of all infants These are seen more frequently in premature and low–birth-weight infants and occur more commonly in girls than in boys Superficial lesions possess a red color, resembling a strawberry or raspberry Deep lesions appear soft, compressible, and often are faintly bluish Mixed lesions may show features
of both superficial and deep hemangiomas A precursor lesion may or may not be noticeable immediately at birth They typically undergo an early rapid growth phase between 5 and 8 weeks old, continue to proliferative phase during the first
4 to 6 months, plateau in growth during the second 6 months, and then begin a slow process of involution that lasts a few years Beta-blockers, specifically systemic propranolol and topical timolol, are used to treat severe hemangiomas of infancy Potential complications include bradycardia, hypotension, hypoglycemia,
