　A case of early esophageal carcinoma is reported here. This patient has had no complaints suggesting the cancer of esophagus. He had been admitted to the hospital because of pleurisy. During hospitalization, the X-ray examination of gastro-intestinal tract was carried out. The esophagus-radiograph indicated an abnormality of lower intrathoracic esophagus, there being an oval shaped filling defect. After the reexamination of X-ray and the esophagoscopic study, resection of the esophagus and esophago-gastrostomy was performed.

　The tumor, which was located at the lower esophagus, measured 2×2cm and it was flat and protruding intraluminally.

　Histologically, typical squamous cancer cells had partially penetrated into submucosal layer, though regional lymphonodi were free from metastasis.

　In routine gastrointestinal X-ray examinations, esophagus should always be examined. For better prognosis of esophageal ophageal cancer we consider it absolutely necessary to look for esophageal carcinoma even during non-symptomatic period by positively advising patients to undergo other necessary examinations whenever the slightest abnormality is detected in X-ray films.

　To date,7 cases of esophageal carcinoma in early stage, including this case, have been reported in Japan.
