Hives (urticaria) on the arm
From DrKoop's partner site on allergy, MyAllergyNetwork.com
Hives (urticaria) are raised, red, itchy welts, seen here on the arm. The majority of urticaria develop as a result of allergic reactions. Occasionally, they may be associated with autoimmune diseases, infections (parasitosis), drugs, malignancy, or other causes.
