You are correct. The dx of SLE was further suggested by dsDNA antibodies >1,000 IU/mL. Dx is guided by the Systemic Lupus International Collaborating Clinics group classification criteria to identify salient features. One fifth of SLE cases will not manifest the minimum criteria when a child is initially seen. These children should remain under surveillance. Cutaneous vasculitis lesions characterized as petechiae or palpable purpura that may blister are usually found on the face, palms, and soles. This pt was treated w/ oral steroids. Seven days later, the rash healed w/ postinflammatory hyperpigmentation.
