Purpose Breast lesions classified as of “uncertain malignant potential” represent a
heterogeneous group of abnormalities with an increased risk of associated malignancy …

Background No consensus exists on whether flat epithelial atypia (FEA) diagnosed
percutaneously should be surgically excised. A systematic review and meta-analysis of the …

rate of pure flat epithelial atypia (FEA) diagnosed at core needle biopsy (CNB). Materials …

Pathologists frequently encounter non‐malignant histological findings in percutaneous core
needle biopsies (CNB s). Standards for the management of patients with lesions such as …

Benign and atypical lesions associated with breast cancer risk are often encountered in core
needle biopsies (CNBs) of the breast. For these lesions, the rate of “upgrade” to carcinoma …

The purpose of this study was to describe and compare the management recommendations
provided in the setting of a high-risk lesion diagnosed on core needle biopsy of the breast at …
