Diagnosis of proliferative breast diseases such as radial scar and papilloma, and proliferative breast diseases with atypia have increased these last years with the augmentation of percutaneous biopsies. Much progress has been made in their histological diagnosis, classification and pathogenesis. Nevertheless, no consensus exists to date on their management, in particular, surgical indications, which remain controversial. Communication between radiologists and pathologists is crucial in patient management.
