Breast lesions are divided histologically into two large groups, malignant and benign. Malignant lesions may be of ductal or lobular origin, with infiltrating ductal carcinoma being the most frequent invasive neoplasm. Benign breast lesions are classified as proliferative, proliferative without atypia and proliferative with atypia. Within the last two classifications are entities that carry a high risk of developing breast carcinoma, such as atypical ductal hyperplasia, radial scar or lobular neoplasia. We review what these entities consist of and what are their fundamental characteristics in image, fundamentally in mammography and ultrasound. When we perform one of these histological diagnoses after a biopsy, it is important to analyze the radiological characteristics and the type of procedure performed (number of cylinders, needle gauge ...) to perform an appropriate posterior management. In some cases the attitude to be followed will be the complete surgical removal of the lesion, while in others a percutaneous excision (through vacuum needle biopsy) or even strict image follow-up may be performed. Through different cases we will show our experience and analyze current literature to remember these entities and reach an adequate management consensus.
