“…Nail alteration in psoriasis is mostly asymptomatic in the early stages and can be its initial presentation, hence examination and evaluation for nail changes routinely is of foremost importance. 1,3,4 Nail psoriasis leads to physical disability, cosmetic disfigurement, and psychological disability, thereby adding to a remarkable decrease in quality of life.…”

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.

“…Nail changes also positively correlated with the severity of disease and presence of arthritis. 16 Psoriatic onycholysis was dermoscopically seen as whitish onycholytic area distally with a proximal characteristic reddish border (40.63%) which was not always visible to the naked eye. The onycholytic edge was dented in 75% while linear in others.…”

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.
