Resumo
As lesões de Cameron são uma causa pouco comum e esquecida de hemorragia digestiva indolente e consequente anemia ferropénica. Caracterizam-se por erosões ou úlceras dispostas sobre as pregas da mucosa gástrica ao nível do hiato diafragmático, em doentes com hérnias do hiato volumosas. A etiologia não está bem esclarecida e o diagnóstico requer elevada suspeição. A resposta ao tratamento médico é variável. Consiste em suplementos de ferro e terapêutica anti-ácida com inibidores da bomba de protões. Apresenta-se um caso clínico ilustrativo desta entidade com apresentação clínica e aspecto endoscópico típicos e com boa resposta à terapêutica médica.
Cameron Ulcers - a forgotten cause of iron deficiency anaemia
Summary
Cameron lesions are an uncommon and frequently overlooked cause of insidious gastrointestinal bleeding and iron deficiency anaemia. They are described as chronic linear erosions or ulcers positioned on the crests of folds at the diaphragmatic impression in patients with a large hiatal hernia. The cause of Cameron lesions remains unclear and its diagnosis requires a high index of suspicion. The response to medical treatment is variable. Treatment is based on oral iron replacement therapy and antisecretory therapy with proton pump inhibitors. A case with typical clinical and endoscopic presentation and good response to medical therapy is reported.
