Achalasia, a rare motility disorder of the esophagus, is generally accepted as a premalignant disorder. This paper presents the case of a 72-year-old male with achalasia and synchronous superficial esophageal cancer who experienced dysphagia symptoms for five years. As achalasia is associated with an increased risk of esophageal cancer, both can be treated simultaneously if detected at the time of diagnosis. Achalasia and synchronous esophageal cancer are rarely detected and treated endoscopically. This paper reports a case of concurrent successful treatment. (Korean J Gastroenterol 2023;82:248-253)
