Breast cancer is considered a malignant tumor with the highest incidence among women and is prone to develop distant metastasis. Small intestinal metastasis of breast cancer, however, is relatively rare. This case report describes a 49-year-old Chinese female patient who presented with small intestinal obstruction and was diagnosed with lobular breast cancer with small intestinal and contralateral breast metastasis. Clinical manifestations, clinicopathological features and potential mechanisms of metastasis, along with diagnosis and treatment, are discussed with a review of the relevant literature. Although small intestinal metastasis is rare in breast cancer, we should keep high alert on the possibility of gastrointestinal metastasis when treating lobular breast cancer patients.
乳腺癌被认为是女性中发病率最高的恶性肿瘤，且易于发生远处转移。然而，乳腺癌小肠转移相对少见。本病例报告描述了一名49岁的中国女性患者，她因小肠梗阻就诊，被诊断为小叶型乳腺癌伴小肠及对侧乳腺转移。本文结合相关文献复习，讨论了其临床表现、临床病理特征、转移的潜在机制以及诊断和治疗。虽然小肠转移在乳腺癌中少见，但在治疗小叶型乳腺癌患者时，我们应高度警惕胃肠道转移的可能性。
