Etiologies of benign esophageal dysphagia are diverse and a panel of clinical and laboratory investigations should be taken to make the right diagnosis. We report herein two cases of benign esophageal dysphagia of non-infectious origin. Imaging tests identified changes similar to malignancies

while only inflamed granulation tissue was discovered in biopsy specimens. Surgical resection was finally applied due to severe symptoms and the histological study revealed only granulation tissue. They were diagnosed as idiopathic cases when all the known non-infectious pathogenesis were carefully ruled out by sound examination results. The differetail diagnosis of benign esophageal dysphagia is quite important as observational data shows that medical therapy should be applied in certain pathogenesis

while esophagectomy might be the most effective solution for other etiologies. Subsequently a comparison of the manifestations of the two cases and those of esophageal dysphagia induced by other non-infectious etiologies was done to shine some light on the differencial diagnosis of benign esophageal dysphagia.
