Diagnostic discordance among histopathological reviewers of melanocytic lesions
May 2024
The management of patient with melanocytic lesions is dependent on the diagnosis with guidelines defining treatment protocols for benign nevi and malignant melanomas. Even though diagnostic discordance and diagnostic ambiguity have been previously established, the real-world impact on patient management is not well understood.Using an exhaustive review process by multiple dermatopathologists and a simulated patient treatment model, this study reveals that diagnostic discordance and ambiguity may be more common that previously reported and identifies significant variation in patient treatment in these lesions.
