Breast malignancies, apart from skin cancer, are the leading cause of cancer from cancer among the female population. Unlike the high prevalence of primary mammary malignancies, metastases to the breast are uncommon, and account for only 0.2-2.7% of all malignancies affecting this organ. We report the case of a 35-year-old woman who sought medical care because of a breast lump. A mammogram suggested a breast tumor, which was biopsied. The histopathological workup resulted in the diagnosis of a metastasis from a medullary thyroid cancer. The authors review the most useful clinical, radiological, histological, and immunohistochemical features concerning extramammary malignancy to the breast.
除皮肤癌外，乳腺恶性肿瘤是女性人群中癌症相关死亡的主要原因。与原发性乳腺恶性肿瘤的高发病率不同，乳腺转移瘤并不常见，仅占影响该器官的所有恶性肿瘤的0.2 - 2.7%。我们报告一例35岁女性因乳腺肿块就医的病例。乳房X光检查提示乳腺肿瘤，遂进行活检。组织病理学检查结果诊断为甲状腺髓样癌转移。作者回顾了关于乳腺外恶性肿瘤转移至乳腺的最有用的临床、放射学、组织学和免疫组化特征。
