Lip reconstruction after tumor excision is challenging because the results must be functional and cosmetic. In this context, Mohs micrographic surgery (MMS) is essential in ensuring maximum tissue preservation, with lower recurrence rates and the possibility of less complicated reconstructions.We report three cases of lip tumors treated with Mohs surgery, whose reconstruction was performed with island advancement flaps (V-Y).The relevance of the correct management of this type of tumor is discussed,highlighting the use of Mohs surgery and V-Y advancement flap,which provide satisfactory aesthetic and functional results.

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.

Skin cancer frequently occurs on the pinna. The three-dimensional conformation and the limited availability of redundant regional skin make the reconstruction of this anatomical area challenging. We report the reconstruction of anti-tragus using an earlobe transposition flap.
