摘要

我们报告了腋窝淋巴结内异位乳腺癌的诊断和治疗经验。患者是一名 65 岁的女性，确诊为乳腺癌和腋窝淋巴结转移。我们为她实施了乳房部分切除术和腋窝淋巴结清扫术。术后病理结果显示，乳房无恶性病变；但其中一个腋窝淋巴结内的结节有良性和恶性混合成分，因此诊断为异位乳腺组织浸润性导管癌。该病例是一种非常罕见的乳腺癌，其恶性程度很难与转移区分开来。

Ectopic Breast Cancer Arising within an Axillary Lymph Node.

We report our experience with the diagnosis and treatment of an ectopic breast cancer arising within an axillary lymph node. The patient was a 65-year-old woman diagnosed breast cancer and axillary lymph node metastasis. We performed a partial mastectomy and axillary lymph node dissection. Postoperative pathology revealed no malignant lesions in the breast; however, a nodule in one of axillary lymph nodes had mixed benign and malignant components, leading to a diagnosis of invasive ductal carcinoma derived from ectopic mammary tissue. This case represents a very rare form of breast cancer, and the malignancy was difficult to distinguish from metastasis.
