description: "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."
