Primary accessory breast cancer is an extremely rare pathology, representing less than 1 % of all breast cancers, and it is found in more than 90 % of cases in the axilla. The diagnosis of accessory axillary breast cancer (AABC) is often late and at an advanced stage with an average delay of 40.5 months. Histological sampling and immunohistochemical results confirm the diagnosis. Most patients are diagnosed with stage II disease or higher, so it is considered to have a poor prognosis. There is no specific management for AABC; it follows the guidelines for orthotopic pectoral breast cancer. We therefore report the case of a 50-year-old woman diagnosed with grade II invasive ductal carcinoma found in accessory axillary breast, treated by wide local resection and sentinel lymph node dissection.
原发性副乳腺癌是一种极其罕见的病理类型，占所有乳腺癌的比例不到1%，且90%以上的病例发生在腋窝。腋窝副乳腺癌（AABC）的诊断通常较晚且处于晚期，平均延迟时间为40.5个月。组织学取样和免疫组化结果可确诊。大多数患者被诊断为II期或更高分期的疾病，因此其预后较差。AABC没有特定的治疗方法；遵循原位胸段乳腺癌的治疗指南。我们在此报告一例50岁女性，其腋窝副乳腺中发现II级浸润性导管癌，接受了局部广泛切除和前哨淋巴结清扫术。
