A 7-year-old boy was referred for evaluation of an acute generalized itchy rash that had developed 6 days before consultation. The eruption appeared on the lateral aspect of the neck and upper trunk area and rapidly extended to the trunk and abdomen in a flexural distribution. His medical history was irrelevant except for contact dermatitis to mercurochrome. No recent febrile episodes, drug ingestion, or associated symptoms were recorded.

Physical examination revealed an apparently healthy boy with a maculopapular, erythematous, symmetrically distributed rash. The eruption, which had a flexural pattern, mainly involved the axillary folds, antecubital fossae, buttocks, and inguinal and perineal areas (Figure 1 and Figure 2). No mucosal lesions were present, and no enlarged lymph nodes were noted. The results of the rest of the physical examination were unremarkable. The patient complained of mild pruritus, which did not improve after oral antihistaminic administration.
