On the other hand, when an allergen causes dermatitis, we call it allergic contact dermatitis.
The most common characteristics of allergic contact dermatitis are red rashes, swelling, itchiness, and blisters that crust or drain fluids.
Neurodermatitis is one of the different types of dermatitis, but it’s quite different from the other kinds we’ve already discussed.
The difference lies in the fact that the problem didn’t originate with the skin. Interestingly, the affected area was formerly normal and healthy; it just developed dermatitis after repeated rubbing and scratching.
Scientists do not know the exact cause of neurodermatitis. Still, reports indicate that the itchy sensation may begin with a simple irritation, such as tight clothing or an insect bite. When the patient starts rubbing the area, it becomes itchier, leading to more scratching.
Afterward, the area becomes irritated and scaly. Moreover, the skin will eventually look darker than the rest of the body.
One of the different dermatitis types is venous eczema or stasis dermatitis. It commonly affects people over 50 or those with poor circulation.
Venous eczema happens due to poor blood circulation that causes fluid build-up in the lower legs. The build-up leaks out of the veins and into the skin, which may result in inflammation.
Patients with stasis dermatitis may observe itching, swelling, and sores, which might ooze or crust. Moreover, the affected area may also be thick and discolored.
