Dermoscopy-guided Mohs micrographic surgery in post-laser basal cell carcinomas: is dermoscopy helpful for demarcation of the surgical margin?

The results demonstrated that lateral margin was mostly controlled within the first MMS stage with dermoscopy. Dermatosurgeons could focus on the deep margin after the first MMS stage; thus, the performance of MMS could be improved with dermoscopic assistance in post-laser BCC patients.
