We report a rare case of breast metastasis of gastric cancer in a 61-year-old female. She was diagnosed as primary gastric cancer with peritoneal dissemination and received systemic chemotherapy after distal gastrectomy for a primary lesion. A tumor developed in her right breast 4 years after the surgery, and was confirmed to be the metastasis from gastric cancer by aspiration cytology. In Japan, there are 25 reports of breast metastasis from gastric cancer. Two possible pathways from gastric lesion were lymphatic and one vascular, but the mechanism of breast metastasis has remained controversial.
我们报告一例61岁女性胃癌乳腺转移的罕见病例。她被诊断为原发性胃癌伴腹膜播散,因原发性病变行远端胃切除术后接受了全身化疗。术后4年她右侧乳房出现肿瘤,经细针穿刺细胞学检查确诊为胃癌转移。在日本,已有25例胃癌乳腺转移的报告。胃癌转移至乳腺可能有两条途径,即淋巴途径和一条血管途径,但乳腺转移的机制仍存在争议。
