Abstract

Onychoscopy is becoming more and more frequently utilized for the diagnosis of nail disorders. It allows visualization of varying details of nails that can be diagnostic of several diseases, in particular periungual and subungual warts and onychomycosis. The onychoscopy criteria for majority of the inflammatory and infective nail disorders are evolving at a rapid pace. Distinctive dermoscopic signs that are exclusive to distal subungual onychomycosis and to traumatic onycholysis have also been described and allow a differential diagnosis from psoriasis. It has now become very essential for all the clinicians to learn the technique of onychoscopy in order to supplement their primary clinical skills.
