Additionally, the study aims to investigate the differences between pediatric and adult patients.Material and Method: The data of 47 patients with pityriasis lichenoides, followed up at the Dermatology Clinic of Ankara Training and Research Hospital between 01.08.2004 and 01.08.2024, were retrospectively analysed. The patients were classified as pityriasis lichenoides chronica and pityriasis lichenoides et varioliformis acuta. Clinical, demographic, and histopathological characteristics, as well as treatment responses, were evaluated. The patients were divided into pediatric (18 years) groups for comparison. In statistical analyses, a p-value of KW - pityriasis lichenoides KW - phototherapy KW - doxycycline N2 - Amaç: Bu çalışmanın amacı, pityriasis likenoides hastalarının klinik ve demografik özelliklerini, histopatolojik bulgularını ve tedavi yanıtlarını analiz etmektir. Ayrıca, pediatrik ve erişkin hastalar arasındaki farklılıkların araştırılması hedeflendi.Gereç ve Yöntem: 01.08.2004 -01.08.2024 tarihleri arasında Ankara Eğitim ve Araştırma Hastanesi Dermatoloji Polikliniği'nde takip edilen 47 pityriasis likenoides hastasının verileri retrospektif olarak incelendi. Hastalar pityriasis likenoides kronika ve pityriasis likenoides et varioliformis akuta olarak sınıflandırıldı. Klinik, demografik ve histopatolojik özellikler ile tedavi yanıtları değerlendirildi. Hastalar pediatrik (18 yaş) gruplarına ayrılarak karşılaştırıldı. İstatistiksel analizlerde p CR - 1. Bellinato F, Maurelli M, Gisondi P, Girolomoni G.
