Margin Reanalysis With 3-Dimensional Micrographic Surgery Technique of Conventional Excision Specimens With Negative Margin Readings.

Introduction: Mohs micrographic surgery technique allows for complete margin analysis of skin tumors, which explains its lower recurrence rates over conventional surgery. Although it is known that routine processing of excision specimens represents less than 0.5% of the margins, a direct comparison with micrographic technique has not been performed so far.
