CASE 1 ›
A 3-year-old boy was brought to our emergency department for evaluation of skin lesions that he’d had for 7 days. The boy would sometimes scratch the lesions, which began on his right flank as erythematous micropapules and later spread to his right lateral thigh and inner arm (FIGURE 1). His lymph nodes were not palpable.
The boy’s parents had been told to use a topical corticosteroid, but the rash did not improve. His family denied fever or other previous infectious or systemic symptoms, and said that he hadn’t come into contact with any irritants or allergenic substances.
CASE 2 ›
A 13-year-old girl came to our emergency department with a pruriginous rash on her right leg and abdomen that she’d had for 4 days (FIGURE 2). The millimetric papules had also spread to the right side of her trunk, her right arm and armpit, and her inner thigh. Before the rash, she’d had a fever, otalgia, and conjunctivitis. We noted redness of her left conjunctiva, eardrum, and pharynx. The girl’s lymph nodes were not palpable. Serologic examinations for Epstein-Barr virus, cytomegalovirus, rubella, parvovirus B19, and Mycoplasma were negative.
