Unusual presentation of systemic lupus erythematosus.

Bullous systemic lupus erythematosus is a rare distinctive subepidermal blistering disorder that can occur in patients with systemic lupus erythematosus (SLE). It is histologically characterized by a neutrophil-predominant infiltrate in the subepidermal region with deposition of immunoglobulins (IgG, IgA, IgM), C3, and auto-antibodies against collagen VII. Herein, we report a case of a 13-year-old girl who presented with bullous SLE and Class III lupus nephritis, which is extremely rare at this age.
