Surprise! Breast Tumors with Unexpected Final Pathology

 

This talk is organized in two parts to discuss pathology cases with similar morphology, but different diagnoses. Part 1 focuses on variants of invasive lobular carcinoma, their prognostic differences, and their mimics. Part 2 focuses on neuroendocrine tumors of the breast, how they are classified and diagnosed, and includes a discussion of small cell carcinoma and adenoid cystic carcinoma, a rare mimic of neuroendocrine tumors in the breast.

Originally presented on February 10, 2015, in Park City, Utah.
