Background: Linear IgA bullous dermatosis (LABD) is a rare autoimmune blistering disease characterized by linear deposition of immunoglobulin A along the subepidermal basement membrane zone. Although it can occur in both children and adults, the disease in pediatric patients often requires careful consideration due to challenges in differential diagnosis and variability in treatment response. Dapsone is considered the first-line treatment; however, in some cases it may be unavailable, contraindicated, or associated with adverse effects, necessitating alternative therapeutic options. Case Presentation In this case report, we present the clinical features, diagnostic findings, treatment course, and outcomes of a 9-year-old girl diagnosed with LABD. The combination of colchicine and systemic corticosteroids resulted in marked clinical improvement, suggesting that this regimen may be a potential alternative treatment for LABD.
