Abstract：
BACKGROUND: Metastatic breast cancer originating in the gastrointestinal tract is a rare occurrence. The limited number of cases has resulted in incomplete understanding of the disease, making it challenging to differentiate from primary breast cancer. While clinical history and immunohistochemical studies can aid in distinguishing between the two, the management principles and pathogenesis of gastrointestinal metastatic breast cancer remain controversial. The scarcity of data has hampered comprehensive knowledge. Our objective is to shed light on this rare disease through our case study.
METHODS: Here, we report a case of breast metastasis from gastric cancer in a 43-year-old woman. This patient was admitted to our hospital with complaints of discomfort in the upper and middle abdomen persisting for two months, as well as black stools for over ten days. She underwent radical distal gastrectomy for gastric cancer, followed by postoperative chemotherapy. Three years later, the patient developed bilateral breast nodules. Imaging studies indicated a high probability of malignancy. She subsequently underwent a right modified radical mastectomy and excision of a left breast mass. Postoperative pathology revealed the right breast tumor was consistent with primary gastric cancer.
CONCLUSIONS: We present a case of breast metastasis from gastric cancer to contribute to the limited foundation of research into this rare disease.

摘要：
背景：起源于胃肠道的转移性乳腺癌很少发生。病例数量有限,导致对该病的认识不完全,这使得与原发性乳腺癌的区别具有挑战性。虽然临床病史和免疫组织化学研究可以帮助区分两者，胃肠道转移性乳腺癌的治疗原则和发病机制仍存在争议。数据的匮乏阻碍了全面的知识。我们的目标是通过我们的案例研究来阐明这种罕见的疾病。
方法：这里，我们报道一例43岁女性胃癌乳腺转移病例。该患者因上腹部和中腹部不适的投诉持续两个月而入院，以及黑色凳子十天以上。她接受了胃癌根治术,其次是术后化疗。三年后,患者出现双侧乳腺结节。影像学研究表明恶性肿瘤的可能性很高。随后，她接受了右改良根治术和左乳房肿块切除术。术后病理提示右侧乳腺肿瘤与原发性胃癌一致。
结论：我们介绍了一例胃癌的乳腺转移病例，为这种罕见疾病的研究提供了有限的基础。
