Background/Purpose Full‐field optical coherence tomography (FFOCT) is an emerging imaging technique for rapid histological analysis. As FFOCT is introduced into the Mohs workflow, it is important to document the effect of tissue freezing on FFOCT images and any effect FFOCT has on frozen sections. Our study aimed to evaluate the changes on FFOCT images after tissue freezing as well as FFOCT imaging effects on frozen sectioning. Methods Six normal skin specimens were imaged using FFOCT and subsequently frozen using a cryostat. The specimens were then reimaged using FFOCT and compared for any differences. To evaluate the effect of FFOCT imaging on frozen sections, five normal skin specimens were bisected and one half was imaged using FFOCT. Both halves underwent frozen sectioning and analysis. Results Significant changes in the fat, sebaceous glands, eccrine glands, and dermal collage and minimal changes in the epidermis were seen after freezing. No effect on frozen sectioning was seen after FFOCT imaging. Conclusion As FFOCT is studied for use in Mohs, clinicians should be aware that freezing prior to imaging introduces significant artifact in the FFOCT image. If possible, specimens should undergo imaging prior to being frozen.
