[Adenocarcinoma of the esophagus (early stage) concomitant with lung cancer--a case report].

A case of early esophageal cancer, 2.5 cm in length, located just above the esophagogastric junction is presented. This cancer seemed to originate from the fundic gland of the esophagus, because it consisted of the submucosal invasion of well-differentiated adenocarcinoma which was almost completely covered with the squamous cell mucosa of the esophagus. This patient was referred to our clinic because of lower to be a small-cell carcinoma of the lung extending to the mediastinum. He died of the lung cancer one year after operation.
