When to use dermoscopy in nail evaluation?
Dermoscopy is useful in the evaluation of all nail disorders.
In case of nail pigmentation dermoscopy allows to distinguish bands to melanocyte activation that have a grey hue from bands due to melanocyte proliferation, which have a brown and contain longitudinal lines. Regular lies characterize benign (lentigo, nevi), whereas lines that are irregular for color, thickness and parallelism characterize malignant lesions.
In case of non-melanocytic nail tumor always examine the nail plate free edge, as this may be the clue for diagnosis, as in onychomatricoma and onychopapilloma.
In inflammatory nail disorders it enhances features that are already visible with naked eyes.
Utilize dermoscopy is in the differential diagnosis of onycholysis of the toenails, as it helps distinguishing toenail onychomycosis, where the proximal border presents spikes from traumatic onycholysis that has a sharp proximal border.
Dermoscopy of the hyponychium is useful to distinguish nail psoriasis, which presents twisted capillary loops, from other causes of onycholysis
