Unilateral pigmented purpuric eruption.
Three cases of unilateral pigmented purpuric eruption (UPPE) occurring in children aged between 7 and 12 years are reported. The lesions were asymptomatic and occurred on the lower limb and torso; one case demonstrated a quadrantic configuration with a sharp midline cutoff. The purpuric component resolved spontaneously within 3 months in all cases, while pigmentation showed partial resolution in the two cases followed up for 12 months. Our cases support previous reports of UPPE being a benign self-limiting condition mainly affecting young patients. The cause is unknown.
