Systemic contact dermatitis due to amethocaine following digital rectal examination.

Systemic contact dermatitis is a dermatitis that may occur in previously sensitized individuals when they are re-exposed to the allergen. Although many drugs have been implicated as a cause of systemic contact dermatitis, local anesthetics derived from caines have been rarely reported. We present a case of systemic contact dermatitis after a digital rectal examination with a urological lubricant containing amethocaine.
