“…We found that the most common manifestation was pitting of the nail plate, which was present in 55.6% of patients with nail psoriasis; this was followed by Beau's line (36.8%) and onycholysis (35.7%). Several other studies showed that the most frequent psoriatic nail feature is pitting . Pits also can be seen in normal individuals as well as patients with chronic eczema, alopecia areata and lichen planus.…”

There are no detailed studies of the prevalence of nail psoriasis and clinical characteristics of psoriatic nail involvement, including nail features associated with disease severity. Therefore, we designed a study to investigate the prevalence and characteristics of psoriatic nail involvement in patients with psoriasis and determine the relationship between psoriatic nail features and severity of nail psoriasis and cutaneous psoriasis. The Nail Psoriasis Severity Index (NAPSI) was used for evaluation of the severity of nail lesions. The presence of nail fold psoriasis (NFP) was also assessed. The severity of psoriasis was evaluated by calculating the Psoriasis Area and Severity Index (PASI). As a result, the prevalence of nail psoriasis was 85.5%. Pitting was the most common clinical feature (55.6%). The severity of nail psoriasis was not affected by medical parameters, although patients with localized pustular psoriasis tended to have more severe nail psoriasis than did those with chronic plaque psoriasis. When comparing the mean NAPSI and the mean PASI according to nail lesions, we found that subungual hyperkeratosis (SH) and NFP were significantly associated with the severity of both nail psoriasis and cutaneous psoriasis. Psoriatic nail changes were most common in the first digit. Conclusively, the majority of patients with psoriasis had psoriatic nail involvement, and Koebner's response seems to be closely related to the induction of nail psoriasis. To limit progression of the disease, psoriatic patients with SH or NFP should be examined thoroughly because those clinical features reflect the levels of severity of both nail and cutaneous psoriasis.

“…The present study showed that the most common nail psoriasis feature was oil drop which was present in 79.6% of the patients with nail psoriasis; this was followed by onycholysis (76.3%), pitting (57.9%), subungual hyperkeratosis (50.7%), crumbling (41.4%), leukonychia and splinter hemorrhages (28.9%) and last red spots (1.3%). There are some reports claiming that the most frequent psoriatic nail feature is pitting [2,6,9,11,17,18]. On the other hand, there are reports assessing that subungual hyperkeratosis is the most common psoriatic nail feature [1,7]; Grover et al [3] found out that onycholysis is the most repeated psoriatic nail feature.…”

Detailed Analysis of Specific Nail Psoriasis Features and Their Correlations with Clinical Parameters: A Cross-Sectional Study

Background:Occurrence rates of specific features of psoriatic nails, as well as the influence of variable clinical parameters on nail involvement in psoriasis, are not determined. Objective:To evaluate the frequency and characteristics of nail involvement in patients with psoriasis and determine the relationship between nail psoriasis and clinical parameters (age, gender, family history, clinical type, age of onset, duration, joint involvement). Methods: 228 psoriatic patients, who had not received any systematic or topical antipsoriatic treatment for at least a year, were consecutively selected to participate in this cross-sectional study. Results: 66.7% of patients had nail psoriasis. A logistic regression model showed that none of the clinical covariates were statistically significant in predicting nail psoriasis. Conclusion: The majority of psoriatic patients presented nail psoriasis. The most common feature was oil drop. There was a difference in the prevalence of each feature between fingernails and toenails. In correlation with clinical parameters, nail psoriasis evolves independently.
