Abstract

Nail dermoscopy (onychoscopy) is being used for a more accurate diagnosis of all nail disorders and has become a routine diagnostic instrument. In daily practice, nail signs can be magnified, and dermoscopy may confirm the clinical diagnosis and guides in management of nail diseases and treatments, permitting a better visualization of symptoms. Onychoscopy is used by the experts in almost all nail diseases. It can be performed dry or with ultrasound gel in order to make the stratum corneum translucent, depending on which part of the nail unit has to be evaluated.
