Overview
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.
Differential Diagnosis
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.[1][2][3][4][5][6][7][8][9][10][11]
