[A case report of early gastric cancer with Paneth-like tumor cells].
A 55-year-old man was given a diagnosis of grade 0IIc type gastric cancer of the midgastric posterior wall following endoscopy of the upper digestive tract, and subsequently underwent distal gastrectomy. Tumor cells resembling Paneth cells were occasionally observed in differentiated adenocarcinoma that had invaded the submucosal layer, the tumor was CD10-positive, and showed differentiation to complete intestinal metaplasia. In addition, p53-positive cells were also occasionally observed. Although complete intestinal metaplasia is associated with a low incidence of malignant transformation, this case was considered to be different from complete intestinal metaplasia, on which a mutation of the gene of p53 is involved in the early period of carcinogenesis.
