Abstract
Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare inflammatory skin disorder, and mucosal involvement is exceptionally uncommon. We present a 15-year-old male who developed PLEVA with facial and mucosal involvement, preceded by fever. Dermoscopy revealed dotted and linear vessels with micaceous scales. Histopathology showed focal parakeratosis, epidermal exocytosis of neutrophils and lymphocytes, and dense inflammatory infiltrates extending into the subcutaneous tissue. The patient responded well to doxycycline, achieving complete resolution, though varioliform scarring and hyperpigmentation remained. This case underscores the rarity of mucosal involvement in PLEVA and highlights the importance of early recognition and treatment to minimize long-term cutaneous damage.
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).
