A healthy 2-month-old, full-term boy presented with a lifelong history of intermittent skin dimpling of the bilateral legs, with occasional involvement of the abdomen and cheeks. Initially, the infant's parents associated a temporal relationship between diaper changes and these skin findings, though further history revealed similar changes with gentle friction, blowing air, or cold air directed at the affected areas. Examination of the patient's skin revealed bilateral skin rippling of his dorsolateral thighs (Figure 1) with full resolution in less than 30 seconds (Figure 2). See Video S1 for dynamic visualization of this phenomenon. There was no evidence of associated erythema, overlying hypertrichosis, or other dermatologic findings. The patient did not appear to be bothered by these episodes and was otherwise well appearing and asymptomatic on examination.
