Abstract
A 78-years-old-woman with early esophageal cancer was reported. She had general fatigue, but dysphagia or other discomforts of the esophagus. The upper G-I X-ray series revealed slight mural rigidity in the middle esophagus. Fiberscopy showed a protruded lesion on the anterior wall of the esophagus 25cm distal from the upper incissors. By means of biopsy, histological diagnosis of squamous cell carcinoma was made. By iodine staining method, an unstained protruded lesion was distinguished cleary, in contrast to the normal esophageal mucosa which was stained black or brown. This was a case in which the in-vasion of the cancer was limited to the mucosa and metastasis was noted in any lymph node or in the other organs. The cancer was only 4×6mm in diameter.
