Figure 1: Dermoscopic follow up of a melanoma in situ. A. Dermoscopy at baseline, showing a small diameter, reticular lesion. B. Dermoscopy image after 1-year follow up, asymmetric enlargement of the lesion is detectable. The lesion was sent to RCM.
Figure 2: RCM of figure 1 lesion at the suprabasal layer. In the red square multiple atypical roundish nucleated cells in epidermis are marked by red arrows. In the purple square multiple dendritic cells and disarranged DEJ are marked by purple arrows.
Figure 3: Dermoscopic follow up of a compound nevus on the back of a 40-years old woman with multiple nevi and previous history of melanoma. The lesion was enlarging symmetrically over 1 year, and was sent to RCM.
Figure 4: A.RCM of figure 3 lesion at the level of the DEJ showing regular edged papillae. B.RCM image in the periphery of the lesion, showing a regular cobblestone pattern. The lesion is currently under follow up with no dermoscopic changes for 3 years.
