We report an extremely rare operative case of early esophageal carcinoma in a 56-year-old male who have been having a congenital esophageal stenosis due to tracheobronchial remnants being left without any treatments.
The patient has a history of frequent vomiting after eating from the childhood and usually complains of passage disturbance. This time the patient was pointed out to have a circumferential stenosis of the lower portion of the esophagus, dilatation of the oral esophagus, and superficial esophageal carcinoma locating in the dilated portion by endoscopic examination at medical checkyp.
Curative operation for the esophageal cancer was performed. Pathologically it was well-differentiated squamous cell carcinoma with the depth of invation into the submucosal layer, and diagnosed as early esophageal carcinoma.
In this stenotic portion, there were bean-sized tracheobronchial remnants containing the cartilage, therefore the muscle layer structure of the esophagus was remarkably disrupted. Moreover, the mucosa surrounding the esophageal carcinoma was recognized as hyperplastic change that indicated chronic inflammation. This means that the chronic stimulation due to the food stasis is correlated to the occurence of the esophageal cancer as same as the case of the esophageal achalasia. No similar cases report could be seen in the domestic and international literature.
