What is a characteristic of Plummer-Vinson (Patterson-Kelly) syndrome?

Plummer-Vinson syndrome, also known as Patterson-Kelly syndrome, is characterized by a triad of symptoms that includes the presence of esophageal webs, dysphagia (difficulty swallowing), and iron deficiency anemia. The esophageal webs are thin membranes that form in the upper part of the esophagus leading to narrowing and obstruction, which causes the swallowing difficulties. This syndrome is typically associated with nutritional deficiencies, particularly of iron, which can lead to anemia and various complications. The presence of webs in the esophagus is a hallmark of the condition, making it a distinctive feature.

In contrast, the other options describe conditions or symptoms that do not align with the clinical presentation of Plummer-Vinson syndrome. For instance, inflammation of the pancreas does not relate to this syndrome, nor does excessive acid production or chronic diarrhea characterize it. Thus, the association with esophageal webs and dysphagia is fundamental to understanding Plummer-Vinson syndrome and highlights its clinical significance.
