Vascular Lesions in the Breast

Course overview

This lecture will cover a broad spectrum of interesting breast pathology including both benign and malignant entities from ten real cases encountered at the University of Utah Department of Pathology and ARUP Laboratories. The focus is loosely on spindled lesions of the breast, infectious lesions of the breast, and other cases with interesting or surprising results resulting from pathologic examination. Topics covered include cystic neutrophilic granulomatous mastitis, pseudo angiomatous stromal hyperplasia, mammary myofibroblastoma, and demodex folliculitis, among others. The goal is a broad overview of lesions that a general pathologist may encounter in day-to-day practice with suggestions about work-up, comments, or clinical significance discussed. Learning Objectives: Review a case-based selection of spindle cell breast lesions while acknowledging the importance and limitations of IHC in this endeavor; Review a case-based selection of clinically relevant infectious findings in breast biopsies; Review some interesting and unexpected findings of (mostly) "interesting" cases in breast pathology and correlate these findings with anatomic distribution of breast tissue
