Histologic Accuracy of Mohs Micrographic Surgery

Area of Science:

• Dermatology
• Pathology
• Surgical Oncology

Background:

• Mohs micrographic surgery maximizes tumor removal while minimizing tissue excision.
• Accurate interpretation of frozen section slides is critical for successful Mohs surgery outcomes.
• Advanced mapping and microscopy are integral to Mohs surgical techniques.

Purpose of the Study:

• To evaluate the congruence of frozen section slide interpretation.
• To confirm agreement between fellowship-trained Mohs surgeons and dermatopathologists.
• To assess the reliability of frozen section slide interpretation in Mohs surgery.

Main Methods:

• Retrospective cohort concordance study.
• Analysis of 1,720 cases over a 10-year period.
• Comparison of frozen section slide interpretations by Mohs surgeons and dermatopathologists.

Main Results:

• A high concordance rate of 99.5% was observed.
• Demonstrated strong agreement in frozen section slide interpretation.
• Confirmed the accuracy of interpretations between the two specialist groups.

Conclusions:

• Fellowship-trained Mohs surgeons and dermatopathologists exhibit significant agreement in interpreting frozen section slides.
• The findings support the reliability of combined interpretations in Mohs surgery.
• This concordance is vital for optimizing patient care and surgical outcomes in Mohs procedures.
