A 59-year-old woman attended a previous hospital complaining of a nodule of the right axilla. Although ultrasonography had shown no evidenceof malignancy, a growth of thenodulewas found on follow-up. Excisional biopsy revealed a primary accessory breast cancer. Because the resected margins were involved, she was referred to our hospital for additional treatment. Based on imaging, both bilateral mammary glands and axillary lymph nodes were reported normal, and distant metastasis was not observed. We performed additional resection of the right axillary tissue around the biopsy site and the right axillary lymph nodedisse ction. Histo-pathological examination revealed the residual invasive ductal carcinoma in the resected specimen. Both the new surgical margins and the lymph nodes were free of disease. Accessory breast cancer is relatively rare, with the incidence being less than 1% of all breast cancers. It is most frequent in the axillary region. Local extensive resection with sufficient surgical margin and axillary lymph node dissection are generally required. This case report presents our clinical experience of accessory breast cancer with some discussion of the literature.
一名59岁女性曾因右腋窝结节前往某医院就诊。尽管超声检查未发现恶性迹象，但随访时发现结节增大。切除活检显示为原发性副乳腺癌。由于切除边缘受累，她被转诊至我院接受进一步治疗。根据影像学检查，双侧乳腺及腋窝淋巴结均报告正常，未观察到远处转移。我们对活检部位周围的右腋窝组织进行了额外切除，并进行了右腋窝淋巴结清扫。组织病理学检查显示切除标本中有残留浸润性导管癌。新的手术切缘和淋巴结均无病变。副乳腺癌相对少见，发病率不到所有乳腺癌的1%。最常见于腋窝区域。通常需要进行具有足够手术切缘的局部广泛切除及腋窝淋巴结清扫。本病例报告介绍了我们对副乳腺癌的临床经验，并对相关文献进行了一些讨论。
