乳腺放射科医生会遇到不寻常的病变，这些病变在文献中可能没有得到很好的描述。世界卫生组织 (WHO) 的肿瘤分类以前基于组织学和分子分类，现已变得越来越多学科。熟悉罕见乳腺病变的影像学特征和基本病理学，以及世界卫生组织目前的分类，可能有助于放射科医生评估活检结果的一致性，并有助于指导罕见乳腺病变的治疗。这篇综述文章对罕见乳腺肿瘤的影像学特征和 WHO 组织学分类进行了基于病例的综述。© Society of Breast Imaging 2024。保留所有权利。如需商业重复使用，请联系 reprints@oup.com 获取转载和转载的翻译权。所有其他权限都可以通过我们网站文章页面上的权限链接通过我们的 RightsLink 服务获得 - 如需了解更多信息，请联系journals.permissions@oup.com。

Breast radiologists encounter unusual lesions, which may not be well described in the literature. Previously based on histologic and molecular classifications, the World Health Organization (WHO) classification of tumors has become increasingly multidisciplinary. Familiarity with imaging features and basic pathology of infrequent breast lesions, as well as their current classification according to the WHO, may help the radiologist evaluate biopsy results for concordance and help direct the management of uncommon breast lesions. This review article provides a case-based review of imaging features and WHO histologic classification of rare breast tumors.© Society of Breast Imaging 2024. All rights reserved.
