In brief: What causes the itch
Atopic dermatitis is an itch that rashes.
Contact dermatitis is a rash that itches. Ad is caused by an internal itch that becomes a rash only after you scratch the skin over and over again. Cd is caused by an external chemical that soaks into the skin and your immune system sends an army of cells to kill all the skin cells that are contaminated with that chemical. That irritates nerves and itches.
