This type of delayed hypersensitivity reaction is known as cell-mediated hypersensitivity. Generally, no reaction is elicited upon the first exposure to the allergen.
Erythema exsudativum multiforme is an immunologically mediated skin reaction or a reaction to viruses or bacteria (10), classified in the group of type-IV delayed cell-mediated hypersensitivity. The minor form is localized on the skin and the mucosa are not involved (1, 9).
(3, 4) However, an immunologic origin (cell-mediated hypersensitivity reaction) is favoured because of the presence of activated helper T lymphocytes expressing interleukin-2 receptors in these lesions.
