What Is Your Diagnosis? PHACE Syndrome

A 6-week-old male infant was referred to the dermatology department for evaluation of enlarging facial lesions noted shortly after birth. The patient was delivered at 36 weeks’ gestation by normal spontaneous vaginal delivery with no perinatal complications. His growth and development were otherwise normal. Physical examination revealed large, bright red, nonconfluent macules and plaques in a bilateral temporal distribution extending medially to both eyelids and laterally to the scalp.
