CLINICAL AND DIAGNOSTIC ASPECTS OF DISCOID LUPUS ERYTHEMATOSUS (DLE)

Abstract

Discoid lupus erythematosus (DLE) is a chronic and limited form of lupus that predominantly affects the skin, characterized by inflammatory lesions that can result in permanent scarring. This article aims to explore the clinical and diagnostic aspects of DLE, identifying the main signs, symptoms, and the most effective methods for its differential diagnosis. The study used a systematic literature review of clinical and dermatological articles, focusing on recent publications that address classification criteria and new diagnostic technologies. Among the methodological procedures adopted, the analysis of specialized medical literature and clinical case studies stands out, in addition to the comparison of different therapeutic approaches. The results indicate that DLE presents typical symptoms, such as erythematous lesions with adherent scales and skin atrophy, and the diagnosis is confirmed through histopathological examinations and the exclusion of other forms of lupus. The research concludes that early diagnosis and proper management are essential to avoid serious complications, such as scarring and permanent disfigurement, and that new diagnostic tools, such as dermoscopy and directed biopsy, have improved diagnostic accuracy.
