Bullous lupus erythematosus is a rare clinical form of lupus. The diagnosis is challenging and involves the exclusion of other subepidermal bullous dermatoses. We present a 21-year-old woman with erythematosus, polycyclic plaques with vesiculobullae along the periphery, creating an erythema gyratum repens-like pattern on acral regions. The cutaneous biopsy, analytical, and autoimmune studies support the diagnosis of systemic lupus erythematosus. Dapsone and glucocorticosteroids were given with prompt resolution of the lesions within two weeks. To our knowledge this is the first case of bullous lupus erythematosus with this atypical acral presentation.
