什么是老年紫癜？

Senile purpura is benign, easy bruising that affects older adults. It’s sometimes called actinic purpura.

This occurs because the skin and the blood vessels become more fragile as we age, making it easier for our skin to bruise from minor trauma. This is different than conditions that cause easy bruising due to bleeding disorders.

Senile purpura is fairly common, affecting about 10％ of people over the age of 50. This percentage increases with age.

The primary symptom of senile purpura is large, purplish red bruises that are most common on the backs of the hands or the forearm. They become a brown discoloration as they fade.

These bruises typically last between one and three weeks before fading. They fade to brown instead of having the typical coloration of a fading bruise, which may look blue, green, or yellow at different healing points. The brown discoloration may fade, but it could be permanent.

While purpuric lesions most commonly occur on the hands and forearms, they can also occur on mucous membranes, including those in the mouth and even in internal organs.

最常见的因素最直接影响老年紫癜的发展是薄薄的，容易受损的皮肤。很长一段时间内的阳光损坏也可以在发展老年紫癜中发挥作用，因为这可以随着时间的推移削弱我们的结缔组织。

影响血管的血管疾病或药物也可以有助于老年紫癜的发展。Diabetes,rheumatoid arthritis, and狼疮may also increase the likelihood of developing the lesions.

Certain drugs, including corticosteroids and aspirin, may exacerbate the lesions.

在大多数情况下，老年人的紫癜从次要的创伤中发展，即使看起来这个人受到严重伤害。

If you’re experiencing a sudden increase in large bruises on your body, make an appointment with your doctor.

Your doctor will ask about your symptoms and medical history and do a physical assessment. If they see that your ecchymoses — or lesions — are painless and restricted to the hands and forearms with no other abnormal bleeding, they’ll likely diagnose you with senile purpura.

在大多数情况下，老年紫癜都没有治疗。然而，有些人不喜欢瘀伤的外观并寻求治疗。

您的医生可以规定局部类视黄醇，使您的皮肤加厚，以防止进一步的皮肤衰老。然后这降低了老年紫癜的风险。然而，维护素有许多可能超过任何潜在益处的副作用。

Protecting your limbs by wearing shin guards can also help prevent minor trauma that causes bruising.

Natural remedies

Taking citrus bioflavonoids twice daily may also be a good natural remedy for senile purpura. One study found that it reduced the purpura lesions by 50 percent in a group of 70 senior citizens.

一 2015 study 还发现，每天两次将表皮生长因子直接涂抹于皮肤上，并减少了研究经历的人民人民的紫癜病变的数量。

对局部维生素K有些兴趣作为老年紫癜的治疗方法。一 study found that applying topical vitamin K after a laser treatment minimized bruising. However, no studies have been done on people who have senile purpura.

Senile purpura is not dangerous and is completely benign, but unless changes are made, the condition is likely to be recurring. Wearing sunblock can help protect your skin from further sun damage.

大多数紫癜病变持续在一到三周之间，尽管在淡化后变色可能是永久性的。您可以与您的皮肤科医生交谈如何减少他们的外表。
