A structured histotechnology curriculum for Mohs micrographic surgery trainees

BACKGROUND: Mohs micrographic surgery achieves high cure rates for skin cancer through immediate histopathologic evaluation of frozen sections, yet histotechnology training for Mohs fellows varies widely across programs and is often learned informally during routine clinical care. This article describes the development and implementation of a structured, competency-based histotechnology curriculum for Mohs surgery trainees. METHODS: We developed a modular laboratory training curriculum incorporating focused didactic instruction, supervised hands-on laboratory experience, and checklist-based competency assessment. In our program, training occurs during two dedicated 8-hour sessions early in fellowship under direct supervision of a senior histotechnologist. The curriculum addresses three domains: laboratory operations and regulatory requirements, tissue processing and cryostat sectioning techniques, and staining with quality assurance. Competency is assessed using a standardized checklist aligned with expectations for trainees directing Mohs laboratories. RESULTS: The curriculum was implemented as a structured training module providing supervised laboratory instruction for Mohs trainees during the fellowship year. Trainees completed competency assessments across checklist domains and demonstrated proficiency in key tasks required for laboratory oversight. The training sessions were completed without disruption of routine clinical workflow. CONCLUSION: A structured, competency-based histotechnology curriculum may provide a practical framework for standardized laboratory training in Mohs fellowship programs.
