Epiluminescence microscopy (dermoscopy) versus visual inspection during Mohs microscopic surgery of infiltrative basal cell carcinoma.

BACKGROUND

The initial stage of Mohs micrographic surgery (MMS) is usually outlined using visual inspection. Newer noninvasive models are available to the Mohs surgeon to determine initial margins before MMS.

OBJECTIVE

To compare the final number of MMS stages performed using dermoscopy and visual inspection of infiltrative basal cell carcinoma (BCC).

METHODS

Forty patients were randomized to two groups (dermoscopy, visual inspection) before MMS for infiltrative BCC. The final number of stages performed was recorded for each group.

RESULTS

There were no statistically significant differences in the final number of stages when using dermoscopy and visual inspection.

LIMITATIONS

Small sample sizes, comparison of different regions on the head and neck, and a single Mohs surgeon were the limiting factors in this study.

CONCLUSIONS

There was no difference in the final number of stages between dermoscopy and visual inspection to determine the margins of previously biopsied infiltrative BCC.
