This 2-day course provides in-depth coverage on all topics including recent advance in pathology informatics, molecular pathology, and practical topics including those commonly encountered in daily diagnostic pathology in a format of didactic lectures and case-based presentations. Our keynote speaker of this year, Dr. Jason Hornick, will update us on the progress in applications of immunohistochemical tools in bone and soft tissue pathology. The course will be presented by national experts across all subspecialties of diagnostic pathology. The course will address the questions and challenges and provide the updates and expert experiences in diagnostic pathology that practicing pathologists encounter in day-to-day practice, help the practicing pathologists to avoid the commonly encountered diagnostic errors and become proficient in different subspecialties, and help residents and fellows with their subspecialty board exam preparations.
