Resumen

Background: Acquired epidermolysis bullosa is a rare and chronic autoimmune subepidermal bullous disease characterized by the formation of autoantibodies against type VII collagen. Presentation in childhood is rare and with several manifestations. Case report: We report the case of a 12-year-old female patient who presented bullous and polymorphic lesions on the chest and extremities of several months of evolution. Due to the characteristics of the skin lesions, a histopathological and direct immunofluorescence study was conducted, confirming the diagnosis of acquired epidermolysis bullosa. Subsequently, corticosteroid and dapsone treatment was administered, with favorable clinical response during follow-up. Conclusions: Acquired epidermolysis bullosa is unusual in pediatric age, so it should be considered in the differential diagnosis of other congenital and acquired bullous diseases of childhood. The definitive diagnosis is performed through an immunofluorescence, study, which allows for rapid and effective treatment to control the disease and avoid permanent sequelae.
