Description

++

  • Eczema is a common group of skin conditions
  • Form of dermatitis
  • A chronic, relapsing, and inflammatory skin condition
  • Results in itchy, inflamed, irritated skin
  • Often has an inherited tendency to develop other allergic conditions such as asthma and hay fever

++

Essentials of Diagnosis

++

  • There are no laboratory tests used to diagnose eczema
  • Clinical features of the disease are used for diagnosis, including the itchiness and the biology and spread (appearance) of the lesions
  • Ruling out other skin diseases like contact dermatitis and seborrheic dermatitis is used to confirm the diagnosis
  • Skin lesion biopsies or skin cultures may be used to rule out other causes

General Considerations

    • Non-allergic with xerosis and occurrence at a young age
  • Extrinsic
    • Generally associated with a medical history (personal or hereditary) of respiratory allergy
