식도 이완불능증 환자에서 발생한 진행성 식도암 1예

Abstract

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.
