      다국어 초록 (Multilingual Abstract)

      Background: Pigmented purpuric dermatoses (PPD) are chronic disorder characterized by distinct petechial hemorrhage and brownish pigmentation that is usually localized on the lower extremities. The cause of PPD was unknown, but several underlying conditions can be associated with PPD. Some reports suggested that venous insufficiency was related to PPD. But, these studies were done on the small number of sample size.
      Objectives: The aim of this study was to investigate the clinical characteristics of PPD and to elucidate the relationships between the venous insufficiency and clinical manifestation of PPD.
      Methods: A total 104 patients diagnosed with PPD in Department of Dermatology, Pusan National University Hospitals from 2006.11 to 2018.08, were retrospectively reviewed. Doppler ultrasonography was performed in 48 patients of PPD.
      Results: The median age was 52.0 years. Venous insufficiency was detected in 31 in 48 (64.5%) patients who were examined by Doppler ultrasonography. Most common involved vein was long saphenous vein (65.4%). There was a significant correlation between the location of involved vein and the local distribution of PPD. Also, presence of venous insufficiency was associated with broad distribution, darker presentation and long disease duration of PPD.
      Conclusion: This is the largest study investigating the relationship between venous insufficiency and clinical characteristics of PPD. This study showed that venous insufficiency can be a clear predisposing factor of PPD
