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