    Abstract:
    We report 2 cases of early gastric cancer arising in hyperplastic polyps. The first case was 6mm in diameter, tub1, in an intestinal phenotype. The second case was 10mm in diameter, pap, in a gastric phenotype. Before resection, their biopsies had been diagnosed as atypical hyperplastic polyps. These cases suggest that small gastric hyperplastic polyps possess a certain malignant potential. If a hyperplastic polyp shows atypia in the biopsy, a complete resection should be considered.
