This will be a comprehensive 2- day advanced course in diagnostic histopathology. Dr John Chan will guide the audience, using his vast experience, through the diagnostic process of disease entities in major organ systems, particularly in but not limited to general surgical pathology, lymphoid, head and neck, endocrine and soft tissue lesions. Dr Chan, in his unparalleledwittypresentations, will demonstrate the approach to surgical pathology diagnosis of difficult cases and how to utilize clinical or morphologic clues (albeit small and “innocent” sometimes) to aid in diagnosis, and more importantly, to avoid pitfalls. This course will be of great value to diagnostic pathologists, from those in training to those with long experience. In fact, this course mayalsojustifiably be re-titled as DIAGNOSTIC CLUES IN SURGICAL PATHOLOGY 101.
