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

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

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

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 …

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 We present a retrospective review of 111 breast core biopsy specimens with flat
epithelial atypia (FEA) and corresponding excision to better understand rates of upgrade …

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 …

Objective: From previous data, pure flat epithelial atypia (FEA) of the breast demonstrated on
core needle biopsy (CNB) was related to malignant upgrading. However, FEA itself is not an …
