ABSTRACT
Abstract Linear IgA dermatosis is a rare subepidermal autoimmune blistering disease characterized by linear deposition of IgA along the basement membrane zone. In the last three decades, many different drugs have been associated with the drug-induced form of the disease, especially vancomycin. We report a case of vancomycin-induced linear IgA disease mimicking toxic epidermal necrolysis. The aim of this work is to emphasize the need to include this differential diagnosis in cases of epidermal detachment and to review the literature on the subject and this specific clinical presentation.

La Dermatosis IgA lineal es una enfermedad vesiculoampollar subepidérmica autoinmune caracterizada por anticuerpos IgA en la unión dermoepidérmica. Es una enfermedad poco frecuente, siendo la mayoría de los casos idiopáticos, pero con reporte de casos por medicamentos, infecciones virales, enfermedades autoinmunes y tumores malignos. Se presentará un caso clínico de Dermatosis IgA lineal causada por Diclofenaco.
Linear IgA dermatosis is an autoimmune subepidermal vesiculobullous disease characterized by IgA antibodies at the dermo-epidermal junction. It is an uncommon disease, with most cases idiopathic, but with case reports caused by drug, viral infections, autoimmune diseases and malignant tumors. A clinical case of Linear IgA dermatosis caused by diclofenac is presented.
