A 2-YEAR-OLD white boy was referred for evaluation of a scalp lesion. The lesion had been present since birth and at that time was bright red. It was located in the left frontotemporal region and grew proportionately with the patient's head. There were no accompanying symptoms or family history of a similar skin condition. The child had become aware of the lesion and kept it covered with hair.
Physical examination revealed a hairless, pale, macular lesion measuring 4.0×1.0 cm (Figure 1). The lesion extended radially from the vertex to the frontotemporal hairline. There were no other skin lesions on the patient's body.
