Purpuric dermatitis

When it comes to purpuric dermatitis, most people have rarely experienced the disease. Although it is a disease of our skin, the cause is not clear. In fact, many people don’t know much about purpuric dermatitis, and often they don’t even realize they have the disease. Therefore, we must protect our skin well.

We must be cautious when treating skin diseases and avoid scratching the itchy areas with our hands. If you suffer from dermatitis, you must seek treatment early to effectively prevent it from continuing to damage your skin. Let’s learn about purpuric dermatitis below.

The morphology of the skin lesions is initially millet-sized, round or polygonal purpuric papules with a smooth surface and rust color. It does not fade when pressed and may turn yellow-brown over time. The lesions are scattered or merged into pieces with unclear edges. The patients are prone to symptoms of purpuric dermatitis in the calves, thighs and lower trunk, with varying degrees of itching.

The cause is unknown. There are reports of familial onset of the disease, and most patients have factors associated with increased local venous pressure, such as varicose veins in the lower limbs or poor venous return in the lower limbs due to long-term standing. The disease occurs due to increased vascular permeability, red blood cell overflow and collapse, leading to hemosiderin deposition.

Oral vitamin C rutin calcium preparations or Chinese medicine for promoting blood circulation and removing blood stasis such as Danshen tablets and Angelica pills, as well as local application of corticosteroid preparations also have certain therapeutic effects. Gravity and increased venous pressure are important local inducing factors of the disease. Therefore, various factors that lead to increased venous pressure and poor venous return in the lower limbs should be avoided, and moderate activities should be performed without standing for long periods of time. Patients with varicose veins should be treated or wear elastic stockings, which also have a certain preventive and therapeutic effect.

It can be seen that once our skin has problems, it will cause great harm to our body, so we must protect our skin well. Purpura dermatitis is a skin disease.
