A 72-year-old woman underwent a distal gastrectomy for gastric cancer 8 years ago. Histopathological examination showed poor differentiated adenocarcinoma. She had no symptom but chest computed tomography (CT) revealed tumor at sternum. A percutaneous needle biopsy under CT was performed and showed poor differentiated adenocarcinoma. Therefore, extirpation was performed. The tumor was located in sternum and left 2nd rib and thought to invade greater pectoral muscle and left lung. The tumor was resected at sufficient margin with surrounding tissues. Compared with tissue of gastric cancer for histopathological examination, sternal tumor had homeomorphous formation and was diagnosed sternal metastasis from gastric cancer. Sternal metastasis from gastric cancer is a rare disease and standard therapy is controversial. In this case, no findings of reccurrence have been found for 8 months after the operation.
一名72岁女性8年前因胃癌接受了远端胃切除术。组织病理学检查显示为低分化腺癌。她没有症状，但胸部计算机断层扫描（CT）显示胸骨处有肿瘤。在CT引导下进行了经皮穿刺活检，结果显示为低分化腺癌。因此，进行了切除手术。肿瘤位于胸骨和左侧第二肋骨，考虑侵犯了胸大肌和左肺。肿瘤与周围组织一起被充分切缘切除。与胃癌组织进行组织病理学检查相比，胸骨肿瘤具有相似的形态，被诊断为胃癌胸骨转移。胃癌胸骨转移是一种罕见疾病，标准治疗方法存在争议。在该病例中，术后8个月未发现复发迹象。
