Pénfigo vulgar mucoso: a propósito de un caso. Revisión de la literatura

Resumo

Introduction: Pemphigus Vulgaris is an autoimmune disease characterized by causing intraepidermal blisters on the skin and mucosa, as a consequence of the aggression of autoantibodies towards various types of desmosomal proteins. The primary eruptive element is the blister, which can appear in coalescence with the consequent formation of erosive-crusted plaques. In 90% of cases lesions affect the oral mucosa, while in 50-70% they are the first manifestation of the disease. Objective: We aim to report a case of Pemphigus Vulgaris and an updated literature review to analyse its etiological factors and treatment options. Clinical case: We present the case of a 71-year-old male patient, smoker, with prediabetic condition and sindrome Guillain Barré referred to the Oral Surgery and Implantology Service of the Virgen de la Paloma Hospital in Madrid with a clinical picture characterized by oral infection. Once the diagnosis of mucosal PV was confirmed, a systemic corticosteroid therapy was established, obtaining almost complete remission of the lesions. After several weeks of treatment, his dermatologist decided to suspend the corticosteroids to carry out unsuccessful immunosuppressant replacement therapy. The recurrence of the lesions, together with the adverse effects caused by the new therapy, forced the reconsideration of the supply of corticosteroids with a positive resolution of the disease. Conclusions: There is no definitive therapeutic strategy for the treatment of Pemphigus Vulgaris. The goal of treatment is to achieve a prolonged clinical remission by supplying corticosteroids. Immunosuppressants have not been shown to be a valid alternative to corticosteroids, but they are a good option if they are supplied together with corticoids in order to reduce their doses.
