Hemangiomas are common in infants, and often appear within the first few weeks of life. Although many infant hemangiomas are unsightly but regress after a few months, others can be large and disfiguring. Until recently, there have been no ideal treatment options, but there has been recent success using propranolol to treat infant hemangiomas. Host Dr. Michael Greenberg explores this exciting new treatment with Dr. Buddy Cohen, professor of dermatology and pediatrics at Johns Hopkins University School of Medicine.
