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

Background Borderline risk lesions such as flat epithelial atypia (FEA) are increasingly
being diagnosed on biopsy. The need for surgery is being debated. In this study, we …

Purpose The malignant upgrade rate of flat epithelial atypia (FEA) diagnosed on core
needle biopsy varies between 0 and 30%. Excision versus observation with radiological …

Flat epithelial atypia of the breast commonly co-exists with atypical ductal hyperplasia,
lobular neoplasia, and indolent forms of invasive carcinomas such as tubular carcinoma …

Flat epithelial atypia (FEA) is an emerging entity of uncertain clinical significance, and
outcome data are sparse. The aim of this study was to evaluate the clinicopathologic …

Abstract Flat Epithelia Atypia (FEA) is a proliferative lesion of the breast where cells
demonstrate columnar change and cytologic atypia. This lesion has been identified as …

Flat epithelial atypia (FEA) and atypical ductal hyperplasia (ADH) are precursors of breast
malignancy. Management of FEA or ADH after image‐guided core needle biopsy (CNB) …

Breast lesions with atypia are a spectra of diseases that confer increased risk of breast
cancer because of an increased probability of finding concomitant cancer after excision, or …

Flat epithelial atypia (FEA) of the breast have a tendency to calcify and, as such, are
becoming increasingly detected by mammography. There is no consensus yet on whether to …

Background: The optimal treatment of flat epithelial atypia (FEA) found on breast core
needle biopsy (CNB) is controversial. We performed a retrospective review of our …
