An 8-year-old girl was brought into our clinic for evaluation of a leg rash on her right lower leg that had been bothering her for 2 months. Another physician had performed a biopsy and diagnosed subacute spongiotic dermatitis, but the rash did not respond to treatment with triamcinolone cream 0.1% twice daily.

The rash was mildly tender and markedly pruritic. The girl had no history of trauma, prior skin conditions, or other areas with a similar rash. Physical examination revealed concentric annular lesions on the right lower leg (FIGURE). The central areas demonstrated a bruised appearance that did not resolve with diascopy.
