DESIGN: Prospective and comparative. SETTING: University of Massachusetts Medical School. PARTICIPANTS: Ninety second-year medical students. INTERVENTION: A 1-hour teaching intervention using a lecture with 2D images (2D group) or using 3D prosthetic mimics of lesions and eruptions (3D group). MAIN OUTCOME MEASURES: Mean scores in the domains of morphology, lesion and rash recognition, lesion and rash management, and overall performance assessed at baseline, immediately after, and 3 months after each group's respective teaching intervention. RESULTS: Immediately after the teaching intervention, the 3D group had significantly higher mean percentage scores than did the 2D group for overall performance (71 vs 65, P = .03), lesion recognition (65 vs 56, P = .02), and rash management (80 vs 67, P = .01). Three months later, the 3D group still had significantly higher mean percentage scores than did the 2D group for lesion recognition (47 vs 40, P = .03). The 3D group better recognized lesions at 3 months compared with at baseline, whereas the 2D group was no better at recognizing lesions at 3 months compared with at baseline. CONCLUSIONS: Despite limited curricular time, the novel teaching method using 3D prosthetic mimics of lesions and eruptions improves immediate and long-term learning outcomes, in particular, lesion recognition. It is also a preferred teaching format among second-year medical students.en-USClinical CompetenceCohort StudiesCurriculumDermatologyDiagnosis, DifferentialEducation, Medical, UndergraduateHumans*Models, AnatomicProgram Evaluation*Prostheses and ImplantsSkin DiseasesCommunity Health and Preventive MedicineDermatologyMedical EducationPreventive MedicinePrimary CareJournal Articlehttps://escholarship.umassmed.edu/fmch_articles/1752667558fmch_articles/175
