We report a case of corrosive stricture of the esophagus (CSE) developing into esophageal cancer and investigate 21 reported cases of CSE including this case in Japan. The patient, a 54-year-old man who had ingested acid for processing papers at the age of 3 years, had felt a disturbance of passage of food or liquid in his throat. After 51 years, he suffered from difficulty in swallowing in his breast. Circulatory stricutres were detected in the upper part of the esophagus and the middle part of the esophagus (Im) by esophagography. Endoscopy showed esophageal cancer of the superficial and slightly depressed (0-IIc) type at the stricture of the Im and its oral area. Esophagectomy was performed. The resected specimen contained both stricutres and esophageal cancer of 0-IIc type in the Im. The pathological finding was moderately differentiated squamous cell carcinoma involving a part of the muscularis propria. He was discharged with no complications on the 36th postoperative day and is well after 12 months. The number of reported cases of CSE developing into esophageal cancer is 9 in males and 12 in females. These cases were compared with reported cases of achalasia developing into esophageal cancer. The mean interval from injury to cancer was 38 years or longer. The incidence of esophageal cancer which occupied the stricture and the oral area in contact with it was 68% or higher.
