副乳腺癌的诊治现状

Current status of diagnosis and treatment of accessory breast cancer

副乳腺癌的发病年龄与乳腺癌相仿，多在40~60岁左右，常以腋下质硬、边界不清的肿块为首发症状；病理组织学检查是该疾病诊断与鉴别诊断重点，病理类型以浸润性癌居多，治疗方式与乳腺癌相同，宜行以手术为主的综合治疗；因其易发生淋巴结转移，预后较差。

The age at onset of accessory breast cancer is around 40 ~ 60,which is closed to that of breast cancer. It usually presents a hard axillary mass with an obscure boundary as its first symptom. Histopathologic examination is the key point of its diagnosis and differential diagnosis. The main pathologic type of accessory breast cancer is the invasive carcino-ma. A comprehensive treatment based on operation is recommended,which is similar to that of breast cancer. The prognosis of accessory breast cancer is poor because it easily causes lymphatic metastasis.
