A 46-year-old man with severe back pain visited our hospital. Magnetic resonance imaging revealed extensive bone metastasis and rectal wall thickness. Colonoscopy revealed circumferential stenosis with edematous mucosa, suggesting colon cancer. However, histological findings of biopsy specimens revealed inflammatory cells but no malignant cells. The patient underwent endoscopic ultrasound, which demonstrated edematous wall thickness without destruction of the normal layer structure. After unsuccessful detection of neoplastic cells by boring biopsies, we performed endoscopic mucosal resection followed by boring biopsies that finally revealed signet ring cell carcinoma. Herein, we present a case and provide a review of the literature.
一名46岁的严重背痛男子前来我院就诊。磁共振成像显示广泛的骨转移和直肠壁增厚。结肠镜检查发现环形狭窄，黏膜水肿，提示结肠癌。然而，活检标本的组织学检查结果显示有炎性细胞，但无恶性细胞。患者接受了内镜超声检查，显示肠壁增厚且水肿，但正常层结构未被破坏。在通过钻取活检未能检测到肿瘤细胞后，我们进行了内镜黏膜切除术，随后再次进行钻取活检，最终发现印戒细胞癌。在此，我们报告一例病例并对相关文献进行综述。
