description This is the case report of a previously healthy four-year-old girl with a history of upper airway infection that was treated with a β-lactam antibiotic. She was seen in the emergency department one month later with vesiculobullous lesions with clear content that were isolated or grouped in rosettes. Direct immunofluorescence showed baseline linear positivity for immunoglobulin A (IgA) (+) and fibrinogen-positive bullous content with absent remaining immunosera expression. The observed results were compatible with linear IgA bullous dermatosis. After confirming the diagnosis and excluding glucose-6-phosphate dehydrogenase (G6PD) deficiency, dapsone was added to the initial treatment with systemic and topical corticosteroids. This case report is a reminder of the importance of a high index of clinical suspicion for this condition to reach a timely diagnosis.
