A 12-year-old boy was seen with a several-month history of mildly pruritic scaly plaques on his whole body. About 4 years previously, he had a milder form of similar skin lesions that had lasted for several weeks and then cleared without treatment. There was neither a family history nor medical history of such lesions. He had no history of atopic dermatitis or other dermatoses.

On physical examination, we found that the plaques were distributed mainly on the seborrheic areas such as trunk, neck, and forehead (Figure 1A). But, malar areas, palms, and soles were spared, and the distal extremities were relatively clear. However, when we tried to remove the plaques, they peeled off easily with an alcohol swab and showed no Auspitz sign.
