Dr. Anita Haggstrom and the Hemangioma Investigator Group developed the Hemangioma Severity Scale (HSS), a reliable scale to measure the severity of infantile hemangiomas. In addition, a Hemangioma Dynamic Complication Scale (HDCS) was developed to measure hemangioma changes over time. Read more about the HSS and HDCS.
