Lobular breast carcinoma in situ

Definition

A non-invasive adenocarcinoma of the breast characterized by a proliferation of monomorphic cells completely filling the lumina. The overall lobular architecture is preserved. It is frequently multifocal (90% in some series) and bilateral. It seldom becomes invasive; however there is an increased risk of infiltrating ductal adenocarcinoma.
