Perplexing Problems in Breast Pathology (and How to Solve them) 2020

This course is designed to eliminate a variety of practice gaps in diagnostic breast pathology. In general, there is a misdiagnosis rate of ~10% in breast biopsies. For some lesions which are notoriously problematic, the misdiagnosis rate is even higher.

Review of the literature and the faculty’s clinical experience as consultant breast pathologists have clearly documented areas in breast pathology that remain diagnostic problems even for experienced pathologists. These include the categorization of proliferative breast lesions, the classification of in situ lesions, papillary lesions, fibroepithelial lesions, spindle cell lesions, vascular lesions, the distinction between invasive and in situ lesions, and the proper classification of a variety of uncommon benign and malignant lesions. In addition, with the frequent use of core needle biopsy of non-palpable breast lesions, pathologists are often faced with the challenge of distinguishing these entities on small specimen samples.

This interactive microscopy course attempts to eliminate diagnostic error by highlighting pitfalls and the approaches to resolving them by using routine microscopic examination of H and E-stained sections and immunostains. The role of newer adjunctive molecular tests will also be discussed where appropriate.
