The value of dermoscopy of the nail plate free edge and hyponychium

Abstract

The non‐invasive examination of the nail unit using a dermoscope is known as onychoscopy. This technique has become increasingly appreciated to facilitate the clinical diagnosis of nail disorders, opening up a valuable second front with a potential to avoid invasive diagnostic procedures. During a nail consultation, the nail unit should always be examined with the aid of a dermatoscope in all its components. The aim of this paper was to provide practical information about onychoscopy of the nail plate free edge and hyponychium, two components of the nail unit difficult to evaluate at naked eye and often forgotten, but of paramount importance.

“…Additionally, avoid prolonged occlusion. Several studied cases may benefit from topical preparation containing great-potency corticosteroid & calcipotriol (7) . Combination treatment with corticosteroids, especially topical betamethasone with calcipotriol, has been studied extensively & is now used as 1st-line therapy for nail psoriasis and bed involvements.…”

“…Fluorouracil: One percent five-fluorouracil solution & five percent cream applied two times a day to matrix area without occlusion for six months enhances pitting & subungual hyperkeratosis (7) .…”

“…In three-six months, both oral & topical PUVA treatments enhanced nail psoriasis. Nail discoloration is potential side effect of PUVA (7) .…”

“…Suggested NB-UVB phototherapy starting dose for adults with generalised plaque psoriasis must be built on minimal erythema dose & defined based on fixed-dose & skin-phototype protocol. For adults with generalised plaque psoriasis, therapy stage of three times a week dosing of NB-UVB phototherapy is suggested (7) . Pregnant studied cases with guttate psoriasis & generalised plaque psoriasis should receive NB-UVB phototherapy.…”

“…Photodynamic therapy: Adults with localised psoriasis, such as palmoplantar & nail psoriasis should not receive photodynamic treatment with aminolevulinic acid & methyl aminolevulinate. There is enough evidence to suggest climatotherapy for therapy of psoriasis (7) .…”
