Abstract
The aim of this article is to present briefly new pathological entities which are recently increasingly commonly used in pathology reports, as well as to discuss their clinical consequences. The new WHO classification of breast diseases includes, inter alia, invasive carcinoma of no special type: this is not a specific entity, but rather a group of malignancies without specific features. The lobular hyperplasia group includes a classical variant and a pleomorphic variant of lobular carcinoma in situ, as well as atypical lobular hyperplasia. The ductal hyperplasia group, according to the current revision of the WHO classification of breast diseases, encompasses: typical (i.e. non-atypical) ductal hyperplasia, columnar cell change, columnar cell hyperplasia, atypical ductal hyperplasia. The mesenchymal breast hyperplasia group includes pseudoangiomatous stromal hyperplasia. We briefly discuss the above mentioned entities together with their respective clinical and therapeutic consequences.
