Quizplus · Accepted Answer

The erythematosus rash on the hands following two days of exposure to the garden suggests Type IV delayed hypersensitivity reaction. Type IV hypersensitivity reactions occur due to the activation of the cell-mediated immune response, which usually occurs after 24 to 48 hours of exposure to the antigen. Clinical manifestations of Type IV hypersensitivity reactions are characterized by erythematous, scaling plaques, and indurations that commonly affect the hands, feet, and face.
