Microglandular adenosis (MGA) of the breast is a glandular proliferation of uncertain malignant potential, which mimics invasive carcinoma due to haphazard infiltrative growth in breast stroma and the lack of a myoepithelial cell layer. The term atypical microglandular adenosis (AMGA) is used when the glandular structures are more crowded, with a back-to-back architecture and higher variation in size and shape; epithelial proliferation, as well as nuclear atypia and mitotic activity, can be present.

Abstract
Microglandular adenosis (MGA) of the breast is a glandular proliferation of uncertain malignant potential, which mimics invasive carcinoma due to haphazard infiltrative growth in breast stroma and the lack of a myoepithelial cell layer. The term atypical microglandular adenosis (AMGA) is used when the glandular structures are more crowded, with a back-to-back architecture and higher variation in size and shape; epithelial proliferation, as well as nuclear atypia and mitotic activity, can be present.File in questo prodotto:
