An 11-year-old boy had a generalized rash of 5 days’ duration. There was no associated fever, malaise, lethargy, headache, arthralgia, or pruritus. The past history included varicella at the age of 2 years. His past health was otherwise unremarkable. Two weeks prior to assessment, his 5-year-old brother developed varicella. On examination, there were numerous discrete, erythematous maculopapules evenly distributed over the trunk and extremities (Figure). Some of the lesions had a crusted surface. The face, scalp, mucous membranes, palms, and soles were spared. There was no lymphadenopathy or hepatosplenomegaly. The physical examination results were otherwise normal.
Multiple erythematous, polymorphous plaques scattered over the buttocks and posterior aspect of the lower extremities.
