Objectives: To demonstrate how the educational presentation and targeted review of cases with discrepant interpretive findings between pathologists can raise awareness for specific diagnostic errors through identification of common overarching patterns of error in interpretive pathology.
Methods: We performed a review of 147 surgical pathology and cytopathology cases of discordances from 23 PowerPoint presentations presented between 2010 and 2017. Pathologists and pathology residents, blinded from the official interpretations, were presented each case and surveyed for their own diagnostic assessments.
