What’s New in Infantile Hemangiomas

Infantile hemangiomas are the most common tumors of infancy. They are benign blood vessel (technically a progenitor cell with neural crest and pericyte origin) tumors that typically grow rapidly then gradually involute. Involute is the term used rather than “disappear” because some can leave a fibrofatty scar. Overall, 92% involute by age 4, which was shown by two recent studies and is different than the classical teaching which was 90% involute by age 9.

IMost hemangiomas are simply followed by the primary care doctor. However, treatment is considered for those at risk for disfigurement. The concern for fibrofatty residue is more likely with hemangiomas that are larger, have a superficial component, have steep borders, or have thick infiltrative dermal involvement. Those located on the central face may have significant disfigurement as the “specific anatomic curves of the lips, nose, and philtrum do not necessarily return to normal contours after becoming distorted” (quoted from Dr. Frieden, UCSF Pediatric Dermatology, expert in hemangioma treatment).

Treatment, if used, is most often topical medication for non-ulcerated hemangiomas with a 92% efficacy and 56% regression rate, i.e. treatment helps the majority of the time but does not necessarily always eliminate the hemangioma. This is deemed at least as good as laser by Dr. Frieden. Injectable and oral (Hemangeol, propranolol) medications are also options. However, oral medications have a higher rate of side effects especially hypoglycemia (low blood sugar) and pre-treatment clearance with a cardiovascular and pulmonary exam would be needed from either the primary care doctor or cardiologist. If your child has a worrisome hemangioma, I look forward to seeing him/her. Please make an appointment for a dermatology consultation at (626) 331-6411.
