Gastric outlet obstruction can be caused by various pathologies, including peptic ulcer disease, gastric polyps, and malignancies. The incidence rate of breast cancer metastasis to the stomach is only 0.3%. We describe a rare case of an 83-year-old female with a remote history of breast cancer who presented with symptoms of nausea and vomiting. She underwent an upper endoscopy, and biopsies revealed chronic gastritis. However, when she presented for the second time with similar symptoms, she underwent endoscopic ultrasound (EUS)-guided biopsies, which clinched the diagnosis of breast cancer metastasis causing gastric outlet obstruction. This case describes the importance of keeping a wide differential diagnosis for the causes of gastric outlet obstruction and the significance of deeper EUS-guided biopsies if initial endoscopic biopsies are inconclusive.

胃出口梗阻可由多种病变引起，包括消化性溃疡病、胃息肉和恶性肿瘤。乳腺癌转移至胃的发生率仅为0.3%。我们描述了一例罕见病例，一名83岁女性，有乳腺癌病史，出现恶心和呕吐症状。她接受了上消化道内镜检查，活检显示为慢性胃炎。然而，当她再次出现类似症状时，接受了内镜超声（EUS）引导下活检，确诊为乳腺癌转移导致胃出口梗阻。该病例说明了对胃出口梗阻病因进行广泛鉴别诊断的重要性，以及如果初始内镜活检结果不明确，进行更深层次EUS引导下活检的意义。
