Background:
Mohs micrographic surgery enables the surgeon to maximize tumor removal while minimizing the amount of tissue being removed using advanced mapping techniques combined with microscopy. Interpretation of frozen section slides is vital to the success of Mohs micrographic surgery.
Objective:
Evaluate and confirm the congruence of frozen section slide interpretation between fellowship-trained Mohs surgeons and dermatopathologists.
Methods:
Retrospective cohort concordance study spanning 10 years (n = 1,720 cases).
Results:
The concordance rate for frozen slide interpretation between fellowship-trained Mohs surgeons and dermatopathologists in this study was 99.5%.
Conclusion:
This study demonstrates agreement between the interpretation of histologic frozen section slides when evaluated by fellowship-trained Mohs surgeons and dermatopathologists.
