Özet
Background and Aim: The use of dermoscopy in nail diseases is quite recent. Dermoscopy allows a better visualisation of abnormalities of the nail bed and matrix in case of atypical clinical features in psoriatic nail. This study aimed to determine the frequency of findings in psoriatic nail by dermoscopic examination, to compare dermoscopy with clinical examination and to investigate the relationships between the indicators of disease severity. Materials and Methods: This study included 40 patients who presented with psoriatic nail. The severity of skin involvement of the disease was determined by the Psoriasis Area Severity Index (PASI) and the severity of nail involvement was determined by the Nail Psoriasis Severity Index (NAPSI). Patients' nails were evaluated both by clinical examination and dermoscopy. Results: The most common dinical and dermoscopic findings were pitting (92.5%) and leukonychia (92.5%), respectively. No statistically significant difference was observed between the clinical and dermoscopic NAPSI scores (p>0.05). No statistically significant relationship was noted between the PASI and the clinical and dermoscopic NAPSI scores (p>0.05). Dermoscopically, dilated, extended capillary vessels were observed in the nail bed but without the evidence of a relationship with disease severity. A positive correlation was noted between the duration of the disease and the duration of nail involvement (p<0.05). There was a statistically significant positive relationship between the duration of nail involvement and the clinical and dermoscopic NAPSI scores p<0.05. Conclusion: Nail dermoscopy was considered to be a preferable method as a supportive and non-invasive procedure prior to biopsy in cases of isolated nail involvement where clinical diagnosis of nail psoriasis is suspicious.
