Growth of infantile hemangiomas (IHs) is such a distinctive clinical feature that it proves helpful as a diagnostic criterion. However, a small minority of IHs have arrested or slow growth. How these arrested hemangiomas (AHs) differ from the more typically proliferative IHs remains unclear. In this retrospective case series, Suh and Frieden demonstrate that AHs have unique clinical morphologic characteristics, with red-blue overtones, blanched halos, and arborizing telangiectasia. In addition, most AHs were found on the lower half of the body, in striking contrast to IHs. This difference in anatomic distribution suggests that the local underlying vasculature may influence hemangioma growth.
