Update in Salivary Gland Pathology
The classification of salivary gland neoplasms can be difficult due to the morphologic overlap between tumor types and the variability in patterns that frequent many of the tumors. The goal of this lecture is to focus on a selection of the common tumors of the salivary gland and illustrate their expected morphologic variability. Recommendations for immunohistochemical panels to help navigate certain differential diagnoses will be addressed. A couple of the newer topics in salivary gland pathology will also be discussed. This will include discussion on the recently described entity Mammary Analogue Secretory Carcinoma and the concept of high grade transformation in salivary gland carcinomas.
Originally presented on February 11, 2016 in Park City, Utah.

Dr. Witt is an assistant professor of anatomic pathology at the University of Utah School of Medicine, where he serves as the residency rotation director for cytopathology. Dr. Witt received his MD at the University of Colorado Denver, School of Medicine and completed his AP/CP pathology residency at the University of Chicago (NorthShore) where he served as the chief resident during his last two years. He also completed a cytopathology fellowship at the University of Utah/ARUP Laboratories, and is board certified in anatomic and clinical pathology, with subspecialty boards in cytopathology. Dr. Witt is a member of the College of American Pathologists Cytopathology Committee, the American Society for Clinical Pathology, and the American Society of Cytopathologists. His research interests include studies related to fine-needle aspiration and head and neck pathology.
After this presentation, participants will be able to:
- Review the different appearances of a selection of salivary gland tumor types.
- Establish an immunohistochemical staining pattern to aid in distinguishing between certain tumors.
- Discuss some newer concepts in salivary gland pathology.
