The Importance of the Pathological Perspective in the Management of the Invasive Lobular Carcinoma.

Background: Invasive lobular carcinomas (ILC) account for 10-15% of all breast cancers and are the second most common histological form of breast cancer. They usually show a discohesive pattern of single cell infiltration, tend to be multifocal, and the tumor may not be accompanied by a stromal reaction. Because of these histological features, which are not common in other breast tumors, radiological detection of the tumor may be difficult, and its pathological evaluation in terms of size and spread is often problematic.

How did radiologists' diagnostic performance has changed in COVID-19 pneumonia: A single-centre retrospective study.
