RESUMO
Introduction@#Epidermolysis Bullosa Acquisita (EBA) is a rare autoimmune blistering disease which presents in the skin and mucous membranes. The decrease in anchoring fibrils in the basement membrane zone causes separation of the epidermis from the dermis, resulting in its blistering presentation. The treatment plan will depend on the severity of the disease. The first-line treatment for mild EBA includes topical corticosteroids and immunomodulators such as dapsone and colchicine; while severe cases of EBA may be given intravenous immunoglobulins, systemic steroids, and immunosuppressants such as azathioprine and cyclophosphamide. @*Case Report@#This is a case of a 50-year-old Filipino male who presented with a 2-year history of vesicles and tense bullae which evolved into papules, plaques and erosions with scarring and milia formation on the scalp and trauma-prone areas of the trunk and extremities. Clinical examination revealed multiple, well-defined, irregularly shaped erythematous papules and plaques with crusts, scales, erosions, pearl-like milia and scarring on the chest, back, upper, and lower extremities. The oral mucosa was moist with some ulcers on the tongue. Histopathologic examination using Hematoxylin and Eosin (H&E) stain revealed the absence of the epidermis with retention of dermal papillae suggestive of subepidermal clefting. Further examination with direct immunofluorescence (DIF) revealed monoclonal immunoglobulin (IgG) deposits demonstrating an intense linear fluorescent band at the dermoepidermal junction, consistent with Epidermolysis Bullosa Acquisita. Overall, the combined administration of prednisone, azathioprine, and colchicine resulted only in transient and incomplete resolution of lesions in this case of EBA.@*Conclusion@#The management of EBA is mostly supportive with the goal of minimizing complications. Combination treatments using steroids, colchicine, and azathioprine have been reported with various results. Its management remains challenging as most cases are refractory to treatment.
