Small fluid filled blisters called vesicles appear on the hands and feet.
They are most common along the edges of the fingers, toes, palms and soles. The vesicles produce intense itching . Scratching leads to skin changes with thickening and an eczematoid appearance. Scratching may also lead to secondary infections . Uninhibited scratching and skin trauma may lead to an eczematoid type reaction which is more difficult to treat and has a longer healing time.
