Join us at The University of Chicago for a Saturday series of dynamic learning and interactive microscopy sessions designed for practicing surgical pathologists and senior trainees. A two-year curriculum has been developed to address each subspecialty in anatomic pathology. The overall focus will be updates on existing entities, descriptions of new diagnoses, and pearls to avoid pitfalls. Through a guided microscopic tour, the January 2018 session will address common intraoperative questions and diagnostic challenges in frozen section pathology, using an organ system-based approach. To make the discussions more meaningful, cases will be posted on our website prior to the session for preview. They will be presented by faculty and discussed with participants in an interactive manner. Participants are encouraged to bring their own challenging cases to share with the group. References will be provided after the event. Additionally, post-discussion questions will be administered for an opportunity to earn SAM credit.
