ABSTRACT
Giant Cell Arteritis is a vasculitis that mainly affects women over 50. The most common manifestations are headache, jaw claudication, and amaurosis. If not diagnosed early, it can lead to rare irreversible ischemic consequences, with tongue necrosis being one of these. We report a case of a previously undiagnosed patient with lateral tongue necrosis who responded well to oral corticosteroid treatment. The diagnosis is clinical, laboratory and histological and may be aided by imaging exams. Initial treatment is with oral corticosteroids, with methotrexate and tocilizumab as alternatives. Diagnostic suspicion and quick start of treatment favorably influence the prognosis of the disease (AU)
Apresentamos um caso de arterite de células gigantes com amaurose, seguida de necrose da língua, diagnosticado clinicamente com boa resposta terapêutica ao corticoide oral. Salientamos que os casos de necrose da língua são extremamente raros. A suspeita diagnóstica de arterite de células gigantes é de fundamental importância e mesmo na impossibilidade de realizar a biópsia de artéria temporal, não se deve retardar o início do tratamento sob pena de acarretar sequelas definitivas ou manifestações mais graves da doença (AU)
