Epidermolysis Bullosa Acquisita Mimicking Linear IgA Bullous Disease in a 5-year-old Child

We present a case of a 5-year-old child with epidermolysis bullosa acquisita, clinically resembling linear IgA bullous disease. The case demonstrates that autoimmune bullous dermatoses in childhood may show a clinical overlap, which makes the diagnosis based on clinical features highly unreliable. Specific immunofluorescence and immunoserological tests are crucial for precise diagnosis - in our case circulating antibodies against collagen VII were detected using ELISA and indirect immunofluorescence on transfected cells. The disease was treated with systemic and topical steroids with excellent results.
