Contact hypersensitivity (CHS) is a murine experimental model of allergic contact dermatitis (ACD). CHS is based on sensitization with reactive hapten by painting the shaved skin of the chest and abdomen, with a subsequent ear skin challenge with a diluted hapten, causing a swelling reaction that is assessed in various ways.
