Abstract: Hypersensitivity reactions occur when the immune system acts in an exaggerated manner leading to tissue damage. Delayed hypersensitivity is an immunologic reaction that is mediated primarily by T cells and monocytes and presents hours to days after the antigen crosses into the skin. The most commonly recognized form of delayed hypersensitivity is contact sensitivity or allergic contact dermatitis. Other subtypes include the classic tuberculin reaction and Jones–Mote responses. Several diseases and conditions have pathologic features of delayed hypersensitivity reactions.
