Optical super-high magnification dermoscopy in the diagnosis of equivocal melanocytic lesions. poor agreement on current terminology and future perspectives

Optical super-high magnification dermoscopy (OSHMD) represents a new advancement in dermoscopy which enables up to 400x magnification, allowing the visualization of structures commonly not observable with 20x conventional dermoscopy. OSHMD has been used in the differential diagnosis between nevi and melanomas, highlighting some discriminating criteria, including cell irregularity in shape and size. Despite the mounting interest concerning this technique, data are still scarce. This paper aimed to describe our experience in a cohort of patients with dermoscopically equivocal melanocytic lesions and to present the previously unreported agreement on OSHMD criteria between different evaluators.
