Difference Between Eczema and Psoriasis
Eczema and Psoriasis are skin diseases and for both these diseases proper cause is still not identified.
Eczema is known as dermatitis, where ‘derm’ refers to skin while ‘-itis’ refers to inflammation.
Symptoms of Eczema are:
- Redness and swelling of skin.
- Itching and dryness of skin.
- Watery discharge from skin.
People with family history of this infection, patients of bronchial asthma and people with weak immune system can have this skin infection. This is mainly caused by allergy to metal or leather and can spread to other parts of the body as well. In infants you can see this as greasy pealing of eyebrows or scalp and is known as seborrhoeic dermatitis. Eczema is also associated with asthma.
In case of Psoriasis, the person may experience joint pain though the skin on the joints may remain unaffected. The lesions are not watery but some people may develop pus in the infected area. In case of eczema the joints are affected and Photo dermatitis, a type of eczema, can get exaggerated with exposure to sunlight.
Both these skin infections can be treated by steroid drugs. If Psoriasis is sever then the affected area can be subjected to ultra violet A rays but these rays are known to cause skin cancer. The therapy is known as PUVA or Psoralen and ultraviolet A phototherapy. Exposure to sunlight is beneficial in case of psoriasis.
Both these skin diseases make the skin look ugly and affect the social life of the person.
