Overview

Dysphagia is distinguished from similar symptoms including odynophagia, which is defined as painful swallowing, and globus, which is the sensation of a lump in the throat. A psychogenic dysphagia is known as phagophobia.

Plummer-Vinson syndrome must be differentiated from other diseases that cause dysphagia such as reflux esophagitis, esophageal carcinoma, systemic sclerosis, esophageal spasm, pseudoachalasia, stroke, esophageal candidiasis and Chagas disease.
