Recurrence of Basal Cell Carcinoma Treated with Surgical Excision and Histopathological Analysis with Frozen Section Technique with Complete Margin Control (CMC-FS): A 15-Year Experience of a Reference Center.

at 5-year follow-up, CMC-FS guided excision of BCCs of the eyelids resulted in recurrence rates equivalent to MMS. Intraoperative microscopic control of all margins reduced the recurrence rate of the upper third of the facial BCCs, correlating with easier reconstruction with better esthetic and functional outcome.
