An otherwise healthy 16-year-old female patient was observed in our department because of a 4-week history of pruritic, nonblanchable purpuric patches and plaques, symmetrically distributed on both lower limbs. The plaques were 2 to 10 cm in diameter and had an annular configuration with central clearing (Figures 1A and 1B). Additional studies, including blood count with platelet count, basic biochemical profile, erythrocyte sedimentation rate, coagulation studies, and autoimmune screening were normal or negative. A punch biopsy specimen was obtained from a lesion (Figure 2).
