Abstract
A 74 year-old man was admitted to the Second Department of Surgery, Kyorin University hospital with chief complaints of dysphagia for 6 months. Under the diagnosis of esophageal carcinoma, surgical resection of esophgus was done. An ulcerative carcinoma, 5×4.5cm in dimension, was seen in the middle thoracic esophagus. The structure of tumor mass was complicated ; histologically mostly being composed of malignant lymphoepithelioma with adenoid cystic carcinoma in the adjoining part. Apart from this main tumor, there was a small node of tran sitional cell carcinoma which developed in the esophageal glands. Their histogenesis was interesting and has been discussed in details in the present communication. We guess that the tumor might be originated from the esophageal glands and their ducts.
