Low-grade Ductal Carcinoma In Situ of the Breast
Flat epithelial atypia (FEA) of the breast
- Flat epithelial atypia (FEA) of the breast typically is a localized alteration involving only few, neighboring terminal ducto-lobular units.
- However, occasionally there are cases with extensive FEA and morphologic evidence of direct transitions between FEA and classical low-grade ductal carcinoma in situ (lg-DCIS).
- There is a direct transitions between FEA and lg-DCIS and FEA can be considered as a part of the low-grade pathway in the development of breast cancer.
