The 2024 annual Division of Translational Toxicology (DTT) Satellite Symposium, entitled "Pathology Potpourri," was held in Baltimore, Maryland, at the Society of Toxicologic Pathology's 42nd annual meeting. The goal of this symposium was to present and discuss challenging diagnostic pathology and/or nomenclature issues.
