Description

++

  • Dermatitis is an inflammation of the skin
  • Dermatitis is a common condition that usually is not life-threatening or contagious
  • It embraces a range of ailments that in most cases are characterized by red, itchy skin
  • Common types of dermatitis include
    • Contact dermatitis: inflammation that occurs when substances touching the skin cause irritation or an allergic reaction
    • Atopic dermatitis or eczema: chronic, relapsing, and inflammatory condition that results in itchy, inflamed, irritated skin
      • These diseases often have an inherited tendency to develop alongside other allergic conditions such as asthma and hay fever
    • Seborrheic dermatitis: common skin disorder occurring in areas rich in sebaceous glands such as the scalp, ears, eyebrows, and chest, causing scaly, itchy, red skin and stubborn dandruff.

Essentials of Diagnosis

++

  • Diagnosis is generally based on medical history and examination of the skin
  • Contact dermatitis: diagnosis is based on medical history, the appearance of the skin, and a history of exposure to irritants or allergens
  • Seborrheic dermatitis: diagnosis is based on history, appearance of the skin, physical, and skin biopsy
  • Atopic dermatitis (eczema): Diagnosis is based on history and appearance of the skin
  • Skin lesion biopsies or skin cultures may be used to rule out other causes

General Considerations

  • Individuals in certain outdoor and manufacturing occupations are at higher risk for exposure to allergens and irritants that may cause dermatitis

  • Individuals often have an inherited tendency to develop other allergic conditions such as asthma and hay fever
