ДИАГНОСТИЧЕСКАЯ ЗНАЧИМОСТЬ ДЕРМАТОСКОПИИ ПРИ РАЗЛИЧНЫХ ФОРМАХ КРАСНОГО ПЛОСКОГО ЛИШАЯ

Relevance. Lichen planus (LP) is a heterogeneous immune-inflammatory disease with pronounced clinical polymorphism, which considerably complicates timely diagnosis and the differentiation of its forms. Traditional biopsy remains the «gold standard», but its invasiveness and limited applicability in mucosal lesions require the development of non-invasive methods. Dermatoscopy, which makes it possible to visualise subclinical signs of inflammation, pigmentation and structural changes, is becoming a key instrument in the early diagnosis of LP. The insufficient standardisation of dermatoscopic criteria and their variability in different forms of the disease determine the need for further study of dermatoscopic patterns in order to increase diagnostic accuracy and optimise the tactics of the clinical management of patients. Aim of the study. To assess the diagnostic significance of dermatoscopy and to determine the specific dermatoscopic signs of the various clinical forms of lichen planus (LP). Materials and methods. The study included 84 patients with clinically confirmed LP. Clinical examination, digital dermatoscopy (HandyScope, DermLite DL4), assessment of dermatoscopic patterns according to the IDS criteria and morphological verification of the diagnosis in 42 patients were carried out. Statistical analysis included χ² and the t-test (p
