Depressed adenoma of the stomach. Conceptual review and study of five cases.
Depressed gastric adenoma is a recently featured lesion, distinguished by a depression in the gastric mucosa, with histologic changes of conventional adenomatous polyp. We observed five cases of depressed gastric adenoma, one of them associated with a peptic ulcer, another with a gastric stump, and yet another with an early gastric carcinoma. None of the cases was detected clinically by radiology or endoscopic study. Endoscopically, this lesion stimulates a peptic ulcer at a re-epithelialization stage or an early carcinoma of the depressed type. Histologically, all the cases showed dysplastic changes of varying degrees, with a relevant risk of malignancy. A similarity is shown to other lesions described in the gastric mucosa.
