Chickenpox in a Child
A pruritic, erythematous rash developed in a 6-year-oldboy over 5 days. The rash erupted in crops; the lesions appearedinitially as rose-colored macules, progressed rapidlyto papules and vesicles, and finally crusted (A). The distributionof the lesions-with the greatest concentrationon the trunk-is typical of chickenpox.

Because of its associationwith toxic encephalopathy in patients with chickenpox,topical or oral diphenhydramine is not recommended.2,3Meticulous attention to hygiene is necessary to preventsecondary bacterial infections, which require topicalor systemic antibiotic therapy. Such secondary infectionsare impetigo and cellulitis.
