A 48-year-old female discovered a mass in her left axilla. A thorough examination resulted in a diagnosis of left invasive lobular carcinoma(ILC)of the accessory mammary gland with wide ductal spread. Considering the wide ductal spread, massive resection of the left axilla mass, left lymph node dissection, and a latissimus dorsi musculocutaneous flap procedure were performed. However, histological analysis revealed ILC measuring 80×50 mm with lymph node metastases(5/23)and extensive cancer spread, resulting in a positive surgical margin. It is important to recognize the characteristics of ILC, axillary accessory breast cancer, and the axilla in a treatment strategy.
一名48岁女性在左腋窝发现一个肿块。经过全面检查，诊断为左侧副乳腺浸润性小叶癌（ILC）伴广泛导管播散。鉴于广泛的导管播散，对左腋窝肿块进行了大块切除、左淋巴结清扫，并实施了背阔肌肌皮瓣手术。然而，组织学分析显示ILC大小为80×50 mm，伴有淋巴结转移（5/23）且癌症广泛播散，导致手术切缘阳性。在治疗策略中，认识ILC、腋窝副乳腺癌和腋窝的特征很重要。
