Epiluminescence micoscopy (ELM) is a noninvasive technique for the diagnosis of pigmented skin lesions (PSLs).^1-4 Epiluminescence micoscopy criteria are all static criteria that can be evaluated for their presence or absence.⁵ We describe a new dynamic ELM approach and describe new dynamic ELM criteria.

Materials and Methods

During the ELM examination of any PSL, the ELM device can be maintained fixed at the surface of the skin. If the device is slightly moved horizontally, parallel to the surface, a dynamic approach is added. The lesion sticks to the ELM device and follows its movement. When there is a papular component, the superficial part of the lesion stays stuck to the ELM device (does not move) whereas the underlying skin structures dissociate from the superficial image. For training purposes this can be performed with a large papular dermal nevus (Figure 1).
