Background:
Pigmented purpuric dermatosis (PPD) is a chronic disorder characterized by distinct petechial hemorrhage and brownish pigmentation. The cause of PPD is unclear, but several underlying conditions are associated with it. Previous reports suggest that venous insufficiency (VI) might be related to PPD; however, a clear correlation remains unelucidated.
Objective:
To elucidate the causal relationship between PPD and VI.
Methods:
A total 118 patients diagnosed with PPD in the Department of Dermatology, Pusan National University Hospital from November 2006 to July 2019 were retrospectively reviewed. Doppler ultrasonography of the lower extremities was performed in 56 PPD patients, who were then divided into two groups: PPD with and without VI. We compared the clinical features between the two groups. In the PPD with VI group, we assessed the correspondence ratios between PPD and VI lateralities, and between the PPD distribution and the veins involved.
Results:
VI was detected in 35 of the 56 patients (62.5%). The PPD with VI group was significantly associated with wider distribution, darker coloration and longer disease duration. There was a positive correlation of laterality between PPD and VI, and between PPD distribution and the vein involved.
Conclusion:
This findings suggest that VI is a clear provoker of PPD.
Insights
Venous insufficiency (VI) is a significant cause of pigmented purpuric dermatosis (PPD). This study found a strong correlation between VI and PPD, suggesting VI provokes PPD development.
Area of Science:
- Dermatology
- Vascular Medicine
Background:
- Pigmented purpuric dermatosis (PPD) is a chronic skin condition with unclear etiology.
- Previous research suggests a potential link between PPD and venous insufficiency (VI), but this relationship requires further clarification.
Purpose of the Study:
- To investigate the causal relationship between PPD and VI.
- To determine if VI is a contributing factor in the development of PPD.
Main Methods:
- Retrospective review of 118 PPD patients.
- Doppler ultrasonography of lower extremities in 56 PPD patients to assess for VI.
- Comparison of clinical features between PPD patients with and without VI.
- Analysis of laterality and distribution correlation between PPD and VI.
Main Results:
- Venous insufficiency (VI) was identified in 62.5% of PPD patients studied.
- PPD patients with VI exhibited wider lesion distribution, darker pigmentation, and longer disease duration.
- A positive correlation was observed between the laterality of PPD and VI, as well as PPD distribution and affected veins.
Conclusions:
- The findings strongly suggest that venous insufficiency (VI) acts as a provoker for pigmented purpuric dermatosis (PPD).
- This study establishes a clear link between VI and PPD, highlighting VI as a key factor in PPD pathogenesis.
