A member asked:

Are there allergic conditions for the skin that are not caused by direct contact with any substance?

Dr. John Chiu answered

Yes: Atopic dermatitis comes first to mind although it is not totally IgE mediated. Rarely, one may developed a contact dermatitis reaction from ingesting that product such as metals present in certain foods. However the latter is rare and not usually well documented. Drug reaction is yet another example.
