Abstract

Background and Design: Nail dermoscopy or onychoscopy refers to the examination of the nail unit which consists of the proximal and lateral nail folds, hyponychium, nail plate and nail bed non-invasively. Nail biopsies which require surgical expertise are invasive procedures that are seldom performed by dermatologists in diagnosis of psoriasis. Nail dermoscopy may offer a distinct advantage by helping avoid nail biopsies in diagnosis of childhood psoriasis. The aim of this study was to evaluate the dermatoscopic features of nail psoriasis in a pediatric group of patients and to compare these findings with healty children. Materials and Methods: A total of 45 pediatric patients with nail psoriasis (23 girls, 22 boys) and 45 healthy children were enrolled in the study group. Patients with active psoriatic skin lesions (confirmed by skin biopsy) who had at least one psoriatic nail feature were considered to have nail psoriasis. Psoriasis Area and Severity Index and Nail Psoriasis Severity Index scores are evaluated. Patients with onychomycosis were excluded. Dermatoscopic examination of all nails was performed using a manual dermatoscope with x10 magnification. χ2 test was used. Results: The most frequent dermatoscopic features in the nail bed and matrix were pitting (62.2%), punctate leukonychia (55.5%), haemorrhages (splinter and/or dot) (40%), distal onycholysis (40%), black filamentous structures (35.5%), trachyonychia (33.3%) and salmon patches (26.6%) while a reddish background with sparse dotted vessels (46.6%) and periungual desquamation (48.8%) were the most frequent findings in the proximal and lateral nail folds and in the adjacent skin, respectively. Conclusion: This study highlights the usefulness of nail dermoscopy in helping the diagnosis of nail psoriasis by avoiding an additional nail biopsy in the pediatric population.

Özet

Amaç: Tırnak dermoskopisi veya onikoskopi, proksimal ve lateral tırnak kıvrımları, hiponişyum, tırnak plağı ve tırnak yatağından oluşan tırnakünitesinin, non-invaziv bir şekilde incelenmesidir. Tırnak psoriazisinin tanısında, cerrahi tecrübe gerektiren invasiv bir işlem olan tırnak biyopsisi,dermatologlar tarafından nadiren uygulanır. Çocukluk çağı tırnak psoriazisinin tanısında tırnak dermoskopisi, tırnak biyopsisinden kaçınmayısağlayarak önemli bir avantaj sağlayabilecektir. Bu çalışmada bir gurup pediyatrik psoriazisli hastada, tırnak psoriazisinin dermoskopi özellikleriniaraştırmak ve bu bulguları sağlıklı çocukların bulguları ile amaçlanmıştır.Gereç ve Yöntem: Tırnak psoriazisi olan 45 hasta (23 kız, 22 erkek) ve 45 sağlıklı çocuk bu çalışmaya dahil edildi. Aktif psoriazis deri lezyonu(deri biyopsisi ile verifiye) ve en az 1 adet psoriatik tırnak tutulumu bulgusu olan hastalar, tırnak psoriazisi olarak kabul edildi. Psoriazis AlanŞiddet İndeksi ve Tırnak Psoriazisi Şiddet İndeksi skorları hesaplandı. Onikomikozlu hastalar çalışmaya dahil edilmedi. İncelemeler manueldermatoskop ile yapıldı (Dermlite DL4 PigmentBoost Plus X10; 3 Gen, San Juan Capistrano, CA, USA). χ2 testi kullanıldı.Bulgular: Tırnak yatağı ve matriksinde en sık izlenen dermoskopi bulgular pitting (%62,2), punktat lökonişi (%55,5), hemorajiler (splinter veyanoktasal) (%40), distal onikoliz (%40), siyah filamentöz yapılar (%35,5), trakiyonişi (%33,3) ve salmon yamaları (%26,6), proksimal ve lateraltırnak kıvrımlarında ise en sık kırmızı zeminde dağınık noktasal damarlar (%46,6) izlenirken, periferdeki deride en sık periungual deskuamasyonizlendi (%48,8).Sonuç: Bu çalışma, tırnak dermoskopisinin, tırnak psoriazisi tanısındaki önemini ve tırnak biyopsisinden kaçınmada yararlılığını vurgulamaktadır.
