Colonic metastases from gastric cancer are a rare phenomenon and sparsely reported in the literature. We report a case of a 59-year-old woman who presented with vague abdominal symptoms and initial computer tomography (CT) imaging suggestive of a colonic apple-core lesion with serial colonoscopic biopsies diagnostic of metastatic signet ring cell gastric adenocarcinoma. This case is unique given the evolving CT and endoscopic findings that suggested a regression in colonic wall thickening in the setting of 5-aminosalicylic acid (5-ASA) use prior to histologic diagnosis.
胃癌的结肠转移是一种罕见现象，文献报道较少。我们报告一例59岁女性，她出现模糊的腹部症状，最初的计算机断层扫描（CT）成像提示结肠苹果核样病变，经系列结肠镜活检诊断为转移性印戒细胞胃腺癌。鉴于在组织学诊断之前使用5-氨基水杨酸（5-ASA）时，CT和内镜检查结果不断变化，提示结肠壁增厚有所消退，该病例具有独特性。
