Ectopic breast tissue includes both supernumerary and aberrant breast tissue. The incidence of supernumerary tissue has been reported as high as 6% depending on the ethnic group studied. The incidence of aberrant breast tissue remains unknown. The development of malignancy within these anomalies is rare. In the following paper, the case report of a patient with an ectopic breast cancer and a second primary cancer of the left anatomic breast is described. A review of the world literature on ectopic breast cancer follows. Specific characteristics of ectopic breast cancer are defined and recommendations for management are made.
异位乳腺组织包括多余乳腺组织和迷走乳腺组织。根据所研究的种族群体，多余乳腺组织的发生率据报道高达6%。迷走乳腺组织的发生率尚不清楚。这些异常情况内发生恶性肿瘤的情况很少见。在以下论文中，描述了一例异位乳腺癌患者以及左侧正常解剖位置乳腺发生第二原发性癌的病例报告。随后对世界范围内关于异位乳腺癌的文献进行了综述。定义了异位乳腺癌的具体特征并提出了管理建议。
