We report a case with an adenocarcinoma mucocellulare and muconodulare
of the esophagus which is limited to the lamina propria mucosa and th
e submucosal layer. The patient, a 74-year-old man had the chief compl
aints of hematemesis and melena. A superficial and protruding (0-I) ty
pe of lesion was found at the lower thoracic portion of the esophagus
by X-ray and endoscopic examination. The surgically resected esophagea
l specimen showed 0-I and predominantly subepithelial (Sep) type. The
tumor is presumed to have arisen from the cardiac glands in the lamina
ro ria mucosa of the lowermost region of the esophagus.
