ermoscopy is a non-invasive technique that allows the visualization of subtle clinical features of the skin surface and appendages details not visible to the naked eye, allowing magnifications of up to 200x. It is widely used for evaluating and diagnosing all nail diseases, as it provides important information. As any other examination, nail dermoscopy (onychoscopy) requires a good knowledge of nail anatomy & physiology and the pathogenesis of the nail diseases, and it is helpful for the diagnosis of numerous nail diseases and tumors.
Nail disorders are defined according to their appearance and the part of the nail affected (from distal to proximal): hyponychium, onychodermal band (ODB), nail bed, nail plate, lateral nail folds (perionychium), lunula (distal part of the matrix), cuticle, nail matrix and proximal nail fold.
All nail disorders can be observed by dermoscopy. Dermoscopic features of nail signs are always very interesting and saving, and may help in understanding nails diseases.
The study of the nail plate surface should be done with dry dermoscopy, since using gel covers surface abnormalities, while observation of color abnormalities requires it in other skin diseases, dermoscopy is not too time-consuming.
Vitiligo is an acquired depigmentary disorder of the skin and mucous membranes, due to loss of cutaneous melanocytes or alteration in their function. It is characterized by circumscribed
