Multiple erythematous-yellow, dome-shaped papules.

Volume 82, Number 5 www.aafp.org/afp American Family Physician 517 A 15-year-old boy presented with papules concentrated on his bilateral forearms, elbows, knees, and trunk that arose suddenly five weeks earlier. The patient reported that the lesions became pruritic after showering. He had no personal or family history of similar lesions and took no regular medications. He was obese and had a family history of hypercholesterolemia, but had no other notable medical history. Physical examination revealed multiple erythematous-yellow, dome-shaped, nonfollicular papules, some with an erythematous halo at the base (see accompanying figure). A few similar lesions were scattered on the abdomen and lower back. Some of the lesions were excoriated from scratching.
