To accurately interpret intraoperative findings in Mohs Micrographic Surgery, it is essential to know the normal tissue histology of different anatomical sites. The freezing sections evaluated by the technique are obtained horizontally, unlike the vertical sections of conventional anatomopathological analysis. According to the literature review, the frozen sections of interest in topographic histology were digitized and detailed from a training Dermatology service case collection.
