You are correct. She was diagnosed w/ infantile hemangioma in its proliferative phase. Infantile hemangioma is the most common vascular tumor of infancy, affecting 5% of infants. The incidence is highest in female and premature infants. Unlike congenital vascular malformations, this benign lesion is typically not present at birth but appears in the first few wks of life as a small red macule. Hemangiomas then follow a 3-phase growth pattern of proliferation, involution, and resolution, during which they typically proliferate rapidly for a period of 3 to 6 mo, and then involute spontaneously, w/ 90% completely disappearing by 9 yrs of age.
