Exuberant pyoderma gangrenosum in a patient with autoimmune hepatitis

Pyoderma gangrenosum is a rare neutrophilic dermatosis,which usually presents as ulcers with erythematous-vi-olaceous undermined edges and a rough base with purulent or sanguinous exudate. it can be primary or associated with an underlying disease. however,rare cases of its association with autoimmune hepatitis have been described in the literature. diagnosis is based on a characteristic clinical picture and ruling out other causes of ulcers. this paper aims to discuss the management of corticosteroid therapy and the importance of local treatment. we report a case with torpid evolution,presented with multiple and deep ulcers in a young patient with autoimmune hepatitis,causing pain and significant disability. we observed complete healing of lesions after two months of successful treatment. © 2017 by anais brasileiros de dermatologia.
