Large hyperplastic polyps of the stomach.

Epithelial polyps of the stomach can be divided into 2 types: adenomatous and hyperplastic or regenerative. Imprecisions in terminology and histologic classification of the reported cases make it difficult to establish the true incidence of each type. The size of gastric polyps has been among the criteria for predicting malignant potential of the lesion. We present 4 patients in whom large, sometimes multiple, gastric masses represented benign hyperplastic polyps. The radiographic and pathologic features of these large gastric polyps which were not associated with carcinoma are reviewed.
