Bullous systemic lupus erythematosus (BSLE) is a rare subset of systemic lupus erythematosus that is often associated with autoimmunity to type VII collagen. We describe a 45-year-old woman with BSLE who presented with vesiculobullous lesions as an initial manifestation of SLE. The patient first noticed a widespread urticarial, erythematous eruption associated with tense blisters, erosions, and crusting. She was diagnosed with bullous pemphigoid and underwent a one-month course of treatment with betamethazone. Because of the appearance of marked proteinuria, a subsequent renal biopsy, and serological tests, the patient was diagnosed with rapidly progressive glomerulonephritis and systemic lupus erythematosus. The patient's IgG circulating antibodies labeled the dermal floor of salt-split skin and recognized type VII collagen in immunoblot studies. Although methylprednisolone pulse therapy for glomerulonephritis did not alleviate the vesicullobullous eruption, treatment with dapsone resulted in dramatic disappearance of the lesions. Cessation of dapsone therapy due to hemolysis with Heinz-body formation did not aggravate the bullous disease. Our case illustrates that a generalized vesiculobullous eruption can be the sole presenting manifestation of SLE. It also emphasizes the close temporal relationship between BSLE and lupus nephritis.

Bullous systemic lupus erythematosus (BSLE) is an autoimmune blistering disease occurring in patients with systemic lupus erythematosus (SLE). It is a rare disease, especially in children. A 14-year-old girl initially presented with fatigue, generalized vesiculobullous skin lesions, and ulcers over the hard palate and oral mucosa. Clinical investigations revealed hematuria and proteinuria, a high erythrocyte sedimentation rate and titer of antinuclear antibody, and anti-double-stranded DNA. Skin biopsy findings were suggestive of BSLE. A renal biopsy confirmed the features of class V lupus nephritis. Based on the clinical features and investigations, a diagnosis of BSLE with nephritis was made. She received methylprednisolone pulse therapy and hydroxychloroquine; however, it did not alleviate the vesiculobullous eruption, so treatment with dapsone started and resulted in the dramatic disappearance of the lesions. Interruption of dapsone due to hemolysis did not aggravate the bullous disease. During follow-up, she had multiple flare-ups of disease and nephritis without rebound of bullous lesions. BSLE is a rare presentation of SLE in children. Differentiating it from other skin bullous diseases and SLE with blister is important for the correct management. The unusual presentation of this disease may delay the diagnosis and therefore requires a high index of clinical suspicion.

Bullous systemic lupus erythematosus (BSLE) is a rare cutaneous autoimmune disorder characterized by rapid, widespread vesiculobullous lesions in patients with Systemic Lupus Erythematosus (SLE). BSLE can present as the initial manifestation of SLE and may be a marker of severe disease. In this case report, we present a case of a 22-year-old African American woman with BSLE and impaired renal function with subsequent nephrotic range proteinuria concerning for lupus nephritis and autoimmune hemolytic anemia, refractory to systemic corticosteroids, immunoglobulin, and mycophenolate mofetil, requiring dapsone after careful desensitization due to prior history of angioedema with sulfa drugs. This case highlights the importance of the prompt recognition of BSLE as the initial manifestations of SLE and illustrates the association of BSLE with severe disease and the benefit of concomitant use of dapsone with corticosteroids and other immunosuppressant drugs, even in patients with a history of sulfa allergy.
