The widespread use of eradication therapy in recent years has reduced the infection rate, indicating that gastric cancer cases diagnosed in the future may be -naïve. The typical endoscopic presentation of signet-ring cell carcinoma, which accounts for the majority of naïve gastric cancer cases, is a discolored, flat, or depressed lesion; it is rarely presented as an elevated lesion. In this study, we treated a patient with elevated signet-ring cell carcinoma in an naïve stomach. Histopathological testing after endoscopic submucosal dissection showed proliferation of fibromuscular tissue in the tumor, which may have caused the formation of the elevated lesion.
近年来根除疗法的广泛应用降低了感染率，这表明未来诊断出的胃癌病例可能是初发性的。印戒细胞癌是初发性胃癌病例中的主要类型，其典型的内镜表现为变色、扁平或凹陷性病变；很少表现为隆起性病变。在本研究中，我们治疗了一名胃内初发性隆起型印戒细胞癌患者。内镜下黏膜下剥离术后的组织病理学检查显示肿瘤中纤维肌肉组织增生，这可能导致了隆起性病变的形成。
