ABSTRACT

Dermoscopy has proven to be a useful diagnostic procedure in pigmented tumours. More recently its application has been extended to other skin diseases, and diseases of the cutaneous annexes such as the hair (trichoscopy) and nails (onichoscopy). The application of dermoscopy in the evaluation of nails disorders is a noninvasive technique that enables the assessment of specific characteristics of the nails: dermoscopy permits better visualization of abnormalities in the nail plate (pigmentation produced by melanocytic and non melanocytic lesions) and bed, and aids detection of the vascular abnormalities in the hyponychium and proximal nail fold (in connective tissue diseases). The most characteristic signs observed with this technique are reported below, describing the patterns of nail pigment of melanocytic and non melanocycit origin, nail diseases like ungueal psoriasis and connective tissue diseases.
