“…These authors aimed to assess the diagnostic value of videodermoscopy for nail psoriasis. In another descriptive dermoscopic study, Nakamura and Costa investigated the most common onychopathies, including onychomycosis, nail psoriasis, nail lichen planus and nail fragility syndrome, in 500 patients [16]. However, these findings were reported as a correspondence, without the details of the demographic and clinical data; therefore, this lack of details prevented us from comparing the results of that study with our findings.…”

IntroductionDermoscopy is a non-invasive imaging method that enables the evaluation of pigmented and non-pigmented skin lesions. More recently, dermoscopy has been recognized as an effective tool in the diagnosis of nail diseases.AimTo evaluate the dermoscopic features of nail psoriasis and to assess the relationship between these features and disease severity.Material and methodsA total of 67 patients with clinically evident nail psoriasis (14 women, 53 men) were prospectively enrolled. Following a thorough clinical examination, patients were graded according to the Nail Psoriasis Severity Index and physician’s global assessment score. A dermoscopic examination of all fingernails and toenails was performed using a videodermatoscope. Mann-Whitney U and χ2 tests were used for statistical analysis, with a significance threshold of p < 0.05.ResultsThe most frequently observed dermoscopic features were splinter haemorrhage (73.1%), pitting (58.2%), distal onycholysis (55.2%), dilated hyponychial capillaries (35.8%) and the pseudo-fiber sign (34.3%). The pseudo-fiber sign, dilated hyponychial capillaries, nail plate thickening and crumbling, subungual hyperkeratosis, transverse grooves, trachyonychia, pitting and salmon patches were positively associated with disease severity.ConclusionsThe pseudo-fiber sign described in this study appears to be a novel dermoscopic feature of nail psoriasis. We have demonstrated positive associations between a number of dermoscopic manifestations and disease severity. Further studies are required to support the present findings.

“…Dermatoscopic examination typically reveals: (i) a whitish discoloration of the nail, (ii) superimposed longitudinal parallel striation, and (iii) jagged proximal edges with spikes (Figure 2A, B). Moreover, small splinter hemorrhages and various nail discolorations (chromonychia) with green, yellow or brown colors may occur [5,9]. Of note, an intense green color of the nail plate severely affected by a mycotic infection often indicates a secondary infection with Pseudomonas species (Figure 3A, B).…”

Pigmented and non-pigmented nail alterations are a frequent challenge for dermatologists. A profound knowledge of clinical and dermatoscopic features of nail disorders is crucial because a range of differential diagnoses and even potentially life-threatening diseases are possible underlying causes. Nail matrix melanocytes of unaffected individuals are in a dormant state, and, therefore, fingernails and toenails physiologically are non-pigmented. The formation of continuous, longitudinal pigmented streaks (longitudinal melanonychia) may either be caused by a benign activation of matrix melanocytes (e.g., as a result of trauma, inflammation, or adverse drug reactions) or by a true melanocytic proliferation (e.g., in a nevus or melanoma). In general, non-continuous nail alterations, affecting only limited parts of the nail apparatus, are most frequently of non-melanocytic origin. Important and common differential diagnoses in these cases are subungual hemorrhage or onychomycosis. In addition, foreign bodies, bacterial infections, traumatic injuries, or artificial discolorations of the nail unit may less frequently cause non-continuous nail alterations. Many systemic diseases that may also show involvement of the nails (e.g., psoriasis, atopic dermatitis, lichen planus, alopecia areata) tend to induce alterations in numerous if not all nails of the hands and feet. A similar extensive and generalized alteration of nails has been reported after treatment with a number of systemic drugs, especially antibiotics and cytostatics. Benign or malignant neoplasms that may also affect the nail unit include glomus tumor, Bowen’s disease, squamous cell carcinoma, and rare collision tumors. This review aims to assist clinicians in correctly evaluating and diagnosing nail disorders with the help of dermatoscopy.
