Abstract

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. © 2016, Oman Medical Specialty Board. All Rights Reserved.
