A 14-YEAR-OLD adolescent boy has had body asymmetry since birth (Figure 1). His left extremities, particularly the leg, are larger than the right extremities, but the discrepancy became more noticeable during puberty (Figure 2). An extensive nevus flammeus is present on the left side of his chest (Figure 3), back, and right posterior aspect of the neck extending to the shoulder (Figure 4). Both feet and the left hand demonstrate asymmetric toe (Figure 5) and finger growth.
