A Case of Esophageal Carcinoma in a Patient with Primary Achalasia / 대한소화기내시경학회지

Achalasia is believed to be a predisposing factor for the development of esophageal cancer. The prevalence rate of esophageal cancer is 1~7% among all patient with achalasia. The presumed mechanism responsible for the development of cancer are food stasis and gastroesophageal reflux. We experienced a case of esophageal carcinoma in a 47-year-old man,who had diagnosed as achalasia ten years ago. Esophagogram, esophagoscopy with biopsy and chest CT scanning can reveal esophageal carcinoma arising in patients with achalasia.
