Metastases to the breast from extramammary tumours are infrequent. The main challenge in diagnosis is differentiating them from primary breast cancer. Radiologically this can be difficult as there are no specific imaging characteristics for metastases to the breast. Cytopathological evaluation, as well as full radiological assessment, is vital to avoid unnecessary surgery. Sources of primary tumours include a wide variety of cancers. In this pictorial review we illustrate a number of the commonest sources of primary tumours including lymphoma, lung, ovarian and cervical carcinoma, intestinal carcinoid and rare cases of Ewing's sarcoma and malignant pigmented melanocytic schwannoma (low-grade malignant melanoma).
乳腺外肿瘤转移至乳腺较为罕见。诊断的主要挑战在于将其与原发性乳腺癌区分开来。从放射学角度来看，这可能具有难度，因为乳腺转移瘤并无特定的影像学特征。细胞病理学评估以及全面的放射学评估对于避免不必要的手术至关重要。原发性肿瘤的来源包括多种癌症。在本图片综述中，我们展示了一些最常见的原发性肿瘤来源，包括淋巴瘤、肺癌、卵巢癌和宫颈癌、肠道类癌以及尤因肉瘤和恶性色素性黑素细胞神经鞘瘤（低度恶性黑色素瘤）的罕见病例。
