 Nineteen cases of esophageal cancer resembling submucosal tumors(7 cases of submucosal cancer and 12 cases of advanced cancer)were evaluated. Clinicopathological studies revealed they were rather more frequent in females and had a high frequency of lymph node metastasis with histological features different from squamous cell carcinoma. There were also well differentiated squamous cell carcinomas surrounded with fibrosis and poorly differentiated squamous cell carcinomas surrounded with lymphocyte infiltration. Classifying them according to shape or form, three influential factors were noted. First was their original location, second was their interstitial reaction, and third was the character of their histological features. In spite of these unique features, they were able to be correctly diagnosed and there was little difficulty in distinguishing them from submucosal tumors.
