Purpose to determine the frequency of malignancy in subsequent breast excisions following
core-needle biopsy (CNB) diagnosis of pure flat epithelial atypia (pFEA) and to evaluate the …

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 …

Objectives: Flat epithelial atypia (FEA) is an increasingly diagnosed breast lesion yet there
remains a paucity of data regarding these findings and their clinical significance. By …

Breast flat epithelial atypia (FEA) often coexists with more aggressive pathology and
excision is currently recommended when diagnosed by core needle biopsy (CNB). Recent …

There are limited data to guide clinical management when flat epithelial atypia (FEA) is
identified in breast needle core biopsies (NCBs). Our objectives were to determine the …

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 (FEA) is a borderline lesion that might represent an early stage in the
development of certain low-grade carcinomas in situ and invasive cancers. There are no …

Background Routine excision of flat epithelial atypia (FEA) of the breast found on core
needle biopsy (CNB) is being questioned and a policy of selective excision of FEA was …

Purpose To determine whether it is appropriate to routinely undertake surgery if flat
epithelial atypia (FEA) or pure flat epithelial atypia (pFEA) is found on large-core biopsy …

To determine whether flat epithelial atypia (FEA) found in isolation on large core vacuum‐
