Just How Many Different Kinds of Dermatitis Are There?
As you may have suspected, there are lots of different kinds of dermatitis, each with a different cause, with some affecting different parts of the body. If you believe you have dermatitis, including any of the skin conditions described below, you should see your doctor.
- Allergic dermatitis may be a bumpy, red, itchy rash with possibly blisters. Allergic dermatitis occurs when your skin comes into contact with something you're allergic to. Common allergens include perfume, latex, pollen, and certain plants like poison ivy.
- Atopic dermatitis usually causes sore, extremely itchy skin that may include blisters. Also called eczema, atopic dermatitis often appears on the insides of the elbows, knees and ankles, as well as on the face and neck. In infants, it tends to occur on the face, scalp, neck and extremities.
