Wrist dermatitis: contact allergy to neoprene in a keyboard wrist rest.

A case of allergic contact dermatitis to a keyboard wrist rest containing neoprene is reported. The patient, who had a history of sensitivity to rubber products, developed an acute vesicular reaction of the palmar aspects of her distal wrists, followed by eczematous patches of her extremities and face. Treatment with prednisone, a 3-week tapering dose (60, 40, 20 mg), cleared the dermatitis. The widespread uses of neoprene are discussed and suggest that neoprene will become a common source of contact dermatitis as the potential sources of exposure increase.
