From: Interobserver reproducibility in the diagnosis of flat epithelial atypia of the breast
Flat epithelial atypia. (a) Medium power shows a variably dilated terminal duct lobular unit lined by cells with hyperchromatic nuclei. As in Figure 3, there is no evidence of architectural complexity, such as bridge formation or micropapillae. (b) The cells are atypical with rounded nuclei and nucleoli. Snouts are prominent.
