A 34-year-old woman presented with a blistering, intensely pruritic rash that had erupted 3 days earlier. Multiple papular lesions were densely clustered on areas of exposed skin. Excoriations were present, but there was no evidence of bacterial infection.

A 58-year-old black woman sought evaluation of areas of increased pigmentation on her cheeks that had been present for many years. Bleaching agents did not lighten the area; new, non–nickel-containing eyeglass frames had no effect. A 3-week course of halobetasol cream failed to fade the hyperpigmentation.
