Intravenous Immunoglobulin in the Management of Lupus Erythematosus Panniculitis.

Lupus erythematosus panniculitis (LEP) is a rare variant of cutaneous lupus erythematosus (CLE). It is characterized by the presence of a chronic inflammatory process involving the deep dermis and subcutaneous tissues. It commonly presents as deep indurated nodules or sharply demarcated plaques. Antimalarial medications are considered first-line therapy for most cases of LEP while systemic corticosteroids are saved for more resistant lesions. Intravenous immunoglobulin (IVIG) is made up of concentrated polyclonal immunoglobulin G (IgG) fractionated from the blood of healthy blood donors. Nowadays, it is used for the treatment of numerous autoimmune and systemic inflammatory diseases. In this case, we report the case of a female with multiple LEP and discoid lupus erythematosus (DLE) lesions refractory to multiple standard therapy modalities that responded dramatically to IVIG.
