The incidence of metastases to the breast from nonbreast carcinoma is less than 1% of all breast cancers; of these, adenocarcinoma of the lung to breast is a small proportion (<0.1% of breast carcinomas). The imaging findings of a case of metastatic lung adenocarcinoma to the breast are presented with a review of the literature. Imaging findings including elastography suggesting the breast mass is not a primary breast cancer are highlighted. The importance of notifying the pathologist that nonbreast metastatic disease is in the differential is discussed. The use of appropriate tumor markers is needed; otherwise, the lesion may be interpreted as a triple negative breast cancer.
非乳腺癌转移至乳腺的发生率在所有乳腺癌中不到1%；其中，肺腺癌转移至乳腺的比例较小（占乳腺癌的<0.1%）。本文报告了一例肺腺癌转移至乳腺的影像学表现，并对相关文献进行了综述。重点介绍了包括弹性成像在内提示乳腺肿块并非原发性乳腺癌的影像学表现。讨论了告知病理科医生鉴别诊断中存在非乳腺转移性疾病的重要性。需要使用合适的肿瘤标志物；否则，该病变可能被误诊为三阴性乳腺癌。
