Abstract
Lichen sclerosus is a chronic, immune-mediated dermatologic disorder primarily affecting the genital skin. Extragenital lichen sclerosus is rare, especially in men. We present a case of ELS in a 23-year-old male with lesions on the left upper extremity that had persisted for seven years. Over time, the lesions gradually spread to the left upper arm and scapular region. These lesions followed a band-like distribution along Blaschko’s lines, without associated pruritus or pain. This unusual presentation posed a diagnostic challenge, highlighting the rarity of such manifestations.
期刊介绍：
Clinical Case Reports is different from other case report journals. Our aim is to directly improve global health and increase clinical understanding using case reports to convey important best practice information. We welcome case reports from all areas of Medicine, Nursing, Dentistry, and Veterinary Science and may include: -Any clinical case or procedure which illustrates an important best practice teaching message -Any clinical case or procedure which illustrates the appropriate use of an important clinical guideline or systematic review. As well as: -The management of novel or very uncommon diseases -A common disease presenting in an uncommon way -An uncommon disease masquerading as something more common -Cases which expand understanding of disease pathogenesis -Cases where the teaching point is based on an error -Cases which allow us to re-think established medical lore -Unreported adverse effects of interventions (drug, procedural, or other).
