Symptoms The symptoms of dermatitis depend on the type of it. There are different types of dermatitis:
  • Atopic dermatitis (eczema). It is a red, itchy rash that usually occurs where the skin flexes. When scratched, the rash can leak fluid and crust over.
  • Contact dermatitis. The rash occurs on the areas where the body has direct contact with the substances that either irritate the skin or cause an allergic reaction, such as poison ivy, soap and essential oils. The red rash may burn, sting or itch. Blisters may develop.
  • Seborrheic dermatitis. It causes scaly patches, red skin and stubborn dandruff on oily areas of the body, such as the face, upper chest and back. In infants, this disorder is known as cradle cap. It can be long-term with periods of remission and flare-ups.
Risk factors There are some factors that can increase your risk of developing dermatitis:
  • Age. Atopic dermatitis (eczema) usually begins in infancy.
  • Allergies and asthma. People who have a personal or family history of eczema, allergies, hay fever or asthma are more likely to develop atopic dermatitis.
  • Occupation. Jobs that put you in contact with certain metals, solvents or cleaning supplies increase your risk of contact dermatitis. Being a health care worker is linked to hand eczema.
  • Health conditions. If you have conditions like congestive heart failure, Parkinson's disease and HIV, you are likely to get seborrheic dermatitis.
