“…Dermoscopy allows for better visualization of the nail bed and nail matrix abnormalities, and detects early or mild, as well as late changes in the disease, as was also seen in the present study [12]. With its routine use in clinical practice, early and late descriptions of skin, nail and hair diseases are being elaborated in literature increasingly.…”

Background: Nail involvement in psoriasis may be assessed clinically, ultrasonologically, and dermoscopically. The aim of this study was to assess the dermoscopic features of nails in psoriasis, compare them with clinical findings, and correlate them with the Nail Psoriasis Severity Index (NAPSI) score. Methods: We recruited 120 patients with psoriatic nail changes for the study. The Psoriasis Area Severity Index (PASI) was used to assess the severity of disease. Clinical and dermoscopic (DermLite DL4, ×10, polarized and non-polarized) nail examination determined NAPSI, modified NAPSI (mNAPSI), and NAPSI determined with dermoscopic findings (dermoscopic NAPSI [dNAPSI] and dermoscopic modified NAPSI [dmNAPSI]) were used to assess severity of nail involvement. Results: Subungual hyperkeratosis (50.8%) and nail plate thickening (56.7%) were the commonest clinical nail changes found, and dermoscopically, they were subungual hyperkeratosis and pitting (68.3% each). The average median with interquartile range of PASI and NAPSI scores were 7.5 [5.7-10.8] and 8.0 [6-12], respectively. NAPSI scores increased significantly with the increase in PASI scores (P < 0.001). A comparison of NAPSI and mNAPSI with dNAPSI and dmNAPSI revealed that NAPSI, mNAPSI, and dNAPSI increased significantly with an increase in PASI scores. dNAPSI scores increased significantly with increased mNAPSI and dmNAPSI, and mNAPSI and dmNAPSI were significantly good predictors of joint involvement in psoriasis. Conclusions: Dermoscopy allows for better visualization of nail findings. Evaluating NAPSI and mNAPSI scores in conjunction with dNAPSI and dmNAPSI increases their helps detect early psoriasis, detection of worsening moderate-to-severe psoriasis (PASI >10) and predict joint involvement and their severity

“…They considered this feature to be specific for psoriatic nails. Similar observations were made by Polat et al 8 and Wanniang et al 2 We too noted this feature in few of our study patients. Also, onycholysis was better visualized with the aid of onychoscope as compared to clinical examination in our study.…”

Background: Nail changes in psoriasis can present as a diagnostic challenge especially in the absence of cutaneous features. They occur in approximately 40% of psoriatics and in 5% as the sole presentation. Onychoscopy as a diagnostic tool aids in better visualization of nail matrix and bed abnormalities in psoriasis patients with nail involvement. Aim: To study onychoscopic features of nails in psoriasis and correlate it clinically using nail psoriasis severity index (NAPSI). Materials and Methods: A total of 60 patients of psoriasis with nail changes were recruited in this hospital based cross-sectional study over a period of one year. Cutaneous severity was assessed using psoriasis area severity index (PASI). NAPSI was used to determine the severity of nail involvement. Nails of the patients with psoriasis were examined clinically and onychoscopically. Statistical analysis was done using the software R i386.3.6.3. Results: Pitting was the most common nail change observed on clinical and onychoscopic examination, seen in 90% and 95% patients respectively. Leuconychia, red spots in lunula, onycholysis, and splinter hemorrhages were better visualized on onychoscopy. A statistically significant higher NAPSI (P < 0.05) was obtained on onychoscopy. There was a positive co- relation between the cutaneous severity of psoriasis and the extent of nail involvement. Conclusion: Onychoscopic examination coupled with NAPSI in nail psoriasis serves as a useful guide to assess the nail involvement and provides a better insight into the subtle nail changes in psoriatics which could have been missed clinically. Limitations: Small study population, lack of age and sex matched control group.

“…15 Pseudo-fiber sign corresponded to arterial and venous ends of capillaries seen in 34.3% cases in a study by Yorulmaz et al 15 However, we failed to observe pseudo-fiber sign owing to the less magnification provided by our dermoscope. Salmon spots, also known as 'oil drop sign' (9.3%) were seen as dull red to orange-red globules in the nail plate while Bhat YJ et al 5 and Polat et al 18 observed salmon spots in 42.9% and 47.5% cases.…”

Background : Nail diseases have always been a challenge for dermatologists. Because diagnosis is not always based on clinical examination and time taken for histopathology KOH or culture examination is long, there has always been a quest for easy and faster method. Onychoscopy, a rapid office-based technique helps see miniscule details, can hence aid in diagnosis. Aim : To study dermoscopic features in various nail disorders. Materials and Methods : 126 patients with clinically evident nail diseases were recruited in the crosssectional descriptive study. After clinical examination, all nails were subjected to dermoscopic examination. Fischer's exact test was applied with a significance threshold of p<0.05. Results : Onychomycosis (n=49) was the commonest nail disorder having spiked pattern as the most common (91.8%) dermoscopic feature. Nail psoriasis (n=32) had onycholysis (84.4%) as the most frequent feature. Nail lichen planus (n=5) had longitudinal fissures (80%) while chronic paronychia (n=5) had erythema and scaling on the PNF (100%). Longitudinal melanonychia (n=5) was associated with regular parallel grey/ brown lines in all cases while trachyonychia had longitudinal ridges in 75% cases. Dilated capillaries (75%), microhemorrhages (75%), capillary dropouts (75%) were seen commonly in systemic sclerosis (n=4). Periungual verruca (n=4) had dermoscopic brownish black dots or globules in 100% cases. Alopecia areata (n=4) showed superficial small pits (100%) most commonly. Conclusion : Dermoscopy helps in picking minute details not visible to the naked eye and hence could serve as an important diagnostic tool.
