Background: Pityriasis rosea (PR) is a common, self-limited cutaneous disease characterized by wide distributed erythematous scaly lesions. The diagnosis is usually based on the clinical features. Objectives: Here, we aimed to investigate the dermoscopic features of PR which may provide helpful clues to the diagnosis. Methods: Demographic, clinical, and dermoscopic features of the patients with PR were retrospectively reviewed, and the findings identified were recorded. Results: A total of 100 lesions from 25 different patients were included in the study. The most common dermoscopic finding was peripheral collarette scale (84%), followed by central yellow with peripheral reddish background (40%), peripheral dotted vessels with patchy distribution (35%), diffuse reddish background (31%), scattered dotted vessels (30%), and irregular distributed scales and red globules (20%). Conclusion: To the best of our knowledge, this is the most comprehensive study focusing on the dermoscopic features of PR. Here, we identified new dermoscopic findings which were not described previously for PR. These findings were irregular linear vessels, blood spots, brown globules, and brown structureless areas. It can be concluded that dermoscopy may provide remarkable clues to diagnosis, especially in atypical presentations of the entity.
