Achalasia is a rare benign esophageal motility disease caused by the impaired relaxation of the lower esophageal sphincter, which results from nerve damage. Patients with achalasia are known to have a high risk of esophageal cancer. Here, we present the case of a patient with achalasia and esophageal cancer in whom the Lugol‐voiding areas (LVAs) could be improved by pneumatic dilation and the extending area of esophagus cancer could become clear. In achalasia patients, LVAs are modified by inflammation and appear wider than their actual size. Moreover, some parts of LVAs in achalasia patients might be reversible by treatments that improve delayed emptying. When the spread of esophagus cancer is unclear due to the detection of numerous LVAs by Lugol chromoendoscopy, the treatments that improve delayed emptying first may be effective in accurately diagnosing the extending area of esophagus cancer.
