Plummer-Vinson syndrome (Paterson-Brown-Kelly) is a rare entity, characterized by dysphagia, esophageal web formation, and iron deficiency anemia. We present the case of a 46-year-old woman with a clinical history of iron deficiency anemia who subsequently presents dysphagia and odynophagia. A subcricoid web that was successfully broken with the endoscope was found. First contact doctors should be familiar with the symptoms of Plummer-Vinson syndrome, and take them into account, when addressing a patient with the classic triad. Since the syndrome is a precancerous condition with high malignant potential, early diagnosis and treatment is of utmost importance for better prognosis.
