Eczema is also known asdermatitis. Eczema is characterized by itchy, erythematous, vesicular, weeping, and crusting patches. The exact cause of eczema is unclear.

Common symptoms of the eczema are redness, skin swelling, itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding. Frequent scratching of the lesions causes further damage to the skin. This is typically treated with moisturizers and steroid creams.

What is Hives?

Hives orurticariaoccurs in relation to过敏原exposure. This is very common withfood allergy. Once the person is exposed to an allergen, it triggers skin associated mast cells to release histamine which is a chemical mediator in an allergic reaction. Histamine causes itching and skin edema giving rise to Hives. This can be associated with other serious allergic manifestations such as angioedema (swelling around the mouth), wheezing due to bronchospasms and more seriousanaphylaxis. Hives can be treated with antihistamines and a short cause of steroids. They are short lasting and respond quickly to the treatment. Sometimes they may persist for few days or recur in few days. Hives is a common presentation to general practitioners or family doctors, and it does not require a long-term follow-up. It is important to avoid exposure to known allergens if hives is recurrent.
