A healthy 3-year-old boy came to our department for a linear asymptomatic eruption that had been present since he was born. He had been unsuccessfully treated with topical steroids. On physical examination, we found numerous tiny whitish flat-topped papules on the anterior trunk with a linear distribution and a few similar lesions on the elbows (Figures 1 and 2). The oral mucosa, palms, soles, and nails were spared. A biopsy was taken from one of the papules on the anterior trunk. The histology slides are shown in Figures 3 and 4. The condition remained unchanged after 6 months of follow-up.
