    【摘要】 原发性腋窝副乳腺包裹性乳头状癌合并乳腺癌的多原发癌在临床上极为罕见。因发病率低且缺乏特征性影像学和临床表现，腋窝副乳腺癌与乳腺癌淋巴结转移常常难以鉴别，容易被误诊。该文报道1例61岁女性患者，因发现右侧腋窝肿物半年余就诊，入院行超声检查提示可能为良性病变，为进一步诊治接受手术切除，术后病理活组织检查确诊为右侧副乳腺包裹性乳头状癌伴导管内癌。1个月后患者发现右侧乳腺结节，辅助检查提示乳腺癌可能性大，术后病理活组织检查确诊为乳腺浸润性癌。结合该例患者的诊治经验进一步回顾相关文献作总结，以提高临床医师的诊治水平。

Due to its low incidence and lacking of specific imaging and clinical manifestations， it is challenging to distinguish axillary accessory breast cancer from breast cancer lymph node metastasis and to the risk of misdiagnosis is high.
