Abstract Purpose The second International Consensus Conference on B3 lesions was held
in Zurich, Switzerland, in March 2018, organized by the International Breast Ultrasound …

Purpose To perform a systematic review and meta-analysis to calculate the pooled upgrade
rate of pure flat epithelial atypia (FEA) diagnosed at core needle biopsy (CNB). Materials …

Flat epithelial atypia (FEA) is an alteration of terminal duct lobular units by a proliferation of
ductal epithelium with low-grade atypia. No consensus exists on whether the diagnosis of …

Background Our aim was to determine upgrade rates of pure flat epithelial atypia (FEA) to
malignancy and higher-risk lesions and to identify patients with FEA at low risk for upgrade …

High-risk breast lesions are characterized by histologic epithelial abnormalities that are
associated with an increased risk of breast cancer, either due to an underestimation by core …

Background Our aim was to compare the pathologic upgrade rates of high-risk breast
lesions (HRLs) on digital two-dimensional mammography (DM) vs digital breast …

Context Management remains controversial due to the risk of upgrade for malignancy from
flat epithelial atypia (FEA). Data about the frequency and malignancy upgrade rates are …

The aim of this study was to analyze the clinicopathological features of patients with flat
epithelial atypia, diagnosed in directional vacuum-assisted biopsy targeting …

High-risk lesions of the breast are frequently encountered in percutaneous biopsy
specimens. While benign, these lesions have historically undergone surgical excision due to …

Columnar cell lesions (CCLs) of the breast comprise a spectrum of morphologic alterations
of the terminal duct lobular unit involving variably dilated and enlarged acini lined by …
