Metastatic lesions to the breast are unusual. We add 21 cases to the previously reported 131 clinical cases. The most common sources are malignant melanomas and the lymphoma/leukemia group. Metastatic lesions to the breast tend to be painless discrete lumps that are generally small at the time of discovery. They usually occur in the upper outer quadrant and are commonly associated with axillary adenopathy. Occasionally, they are the initial manifestation of an occult extramammary primary cancer. Prognosis is poor but appears slightly improved since availability of more refined chemo- and immunotherapeutic regimens. The clinical, pathologic, and radiographic features of this problem are described.
乳腺转移瘤并不常见。我们在之前报道的131例临床病例基础上又增加了21例。最常见的原发部位是恶性黑色素瘤以及淋巴瘤/白血病组。乳腺转移瘤往往表现为无痛性孤立肿块，发现时通常较小。它们通常发生在外上象限，常伴有腋窝淋巴结肿大。偶尔，它们是隐匿性乳腺外原发癌的首发表现。预后较差，但自从有了更精细的化疗和免疫治疗方案后，预后似乎略有改善。本文描述了该疾病的临床、病理和影像学特征。
