A 6-year-old boy was brought for medical evaluation when he broke out with innumerable pea-sized and shaped, asymptomatic red papulonodules on cheeks, buttocks, and upper thighs. The week before onset of the rash, the child had not been feeling well, and had complained of chills, nausea, and a sore throat. One objective temperature measurement showed 102.8 °F.

What diagnostic clue does the rash morphology offer?
