Dr. Jason Lee has written and presented on how we think, cognitive bias in medical diagnosis, and errors in the pathologic pathway of a biopsy from clinic to final report. The latter was recently published in the Journal of Cutaneous Pathology.  It is truly a pleasure to hear Dr. Lee talk with ease about errors, including his own. Dr. Jason B. Lee, MD is Professor, Director of the Jefferson Dermatopathology Center, Director of the Dermatopathology Fellowship, and Director of the Jefferson Pigmented Lesion Clinic at Jefferson Medical College of Thomas Jefferson University. He interned at the University of California, Irvine and then did his residency and fellowship at Thomas Jefferson University Hospitals. He has a recent article in the Journal of Cutaneous Pathology that focuses on error in the pathologic diagnostic pathway.
