On March 11, 2026, the Duke Pathology Interest Group hosted “How is a Diagnosis REALLY made? -- from Biopsy to Breakthrough.” The event aimed to introduce first-year medical and Pathologists’ Assistant (Path A) students to the nuances of the diagnostic process through case studies presented by Pathology Senior Vice Chair Rex Bentley, MD, and Assistant Professor Jeffrey Arnold, MD.
Through these cases, students were given a glimpse into the diagnostic reasoning of a pathologist as each case unfolded. Many of the examples illustrated how highly specific pathological diagnoses can guide targeted therapies and lead to improved patient outcomes, highlighting the close relationship between pathology and precision medicine. Bentley and Arnold also described the roles of histologic stains, molecular testing, and other advanced diagnostic techniques in navigating complex cases and reaching a final diagnosis.
There was a robust turnout, with 10 medical students and one Path A student. Though not every participant will pursue pathology as a career, the event provided attendees with a deeper appreciation for the methods and reasoning that underpin diagnostic medicine. Duke Integrative Immunobiology student Jon Messerschmidt and Duke medical student Ashley Cummings led the event. Duke University Professor of Pathology and Director of Undergraduate Medical Education Andrea Deyrup, MD, PhD, served as faculty advisor.
The focus of the Duke Pathology Interest Group is to foster student interest in pathology. It hosts events that showcase the wide scope of pathology practice, including laboratory tours, brain‑cutting sessions, FNA workshops, and more. Additionally, the group partners with the preclinical instructors to create review sessions on pathology topics.
