Abstract

An endoscopically resected case of the gastric hyperplastic polyp with malignant transformation into signet ring cell type carcinoma is reported. A 58-year-old male, who had a past history of subtotal gastrectomy for gastric ulcer 11 years earlier, visited our hospital because of epigastic discomfort. Endoscopic examination revealed a semipedunculated polyp on the anterior wall of the fornix in the remnant stomach, while the biopsied material disclosed signet ring cell type carcinoma. With this histological evidence, we decided to perform endoscopic resection for the lesion. Grossly, the polyp was completely resected including the normal mucosa at the resected margin. Histological examination demonstrated hyperplastic polyp with inclusion of a cluster of signet ring cell type carcinoma cells in the central part. The ulcer consequent to endoscopic resection was healed 3 months later, and there was no sign of local recurrence during follow-up period of 8 months.
