Background
Full‐field optical coherence tomography (FF‐OCT) is a new noninvasive imaging technique that can see down to the cellular level without tissue preparation or contrast agents.
Objective
To use FF‐OCT to image Mohs micrographic surgery specimens and verify the ability of a dermatopathologist to identify or exclude malignancy.
Materials and Methods
Two Mohs surgeons supplied 18 Mohs sections from 11 patients. Each section was scanned using the FF‐OCT, and a dermatopathologist blinded to the diagnosis examined the images for malignancy. The FF‐OCT images were then compared with the intraoperative hematoxylin and eosin (H&E)‐stained frozen sections for concordance.
Results
All 9 FF‐OCT images interpreted as negative for malignancy were in agreement with the H&E frozen sections. Six of the remaining FF‐OCT images were correctly interpreted as positive for malignancy, and three were deferred because malignancy could not be confirmed or excluded.
Conclusion
Malignancy in Mohs sections can correctly be identified or excluded using FF‐OCT. Although not ready for clinical use in its current state, FF‐OCT has the potential to be incorporated into the Mohs workflow in the future.
