Abstract
Nickel-induced systemic contact dermatitis is rare. Herein we report a case of nickel-induced systemic contact dermatitis following use of a metal tracheostomy cannula. n 84-year-old female patient with a history of intolerance to costume jewelry presented diffuse pruritic erythematous rash 72hours after tracheostomy cannula insertion. Dimethylglyoxime testing of the metal tracheostomy cannula was positive and patch testing confirmed nickel sensitization. This is thus a case of nickel-induced systemic contact dermatitis caused by the release of nickel sulfate from a metal tracheostomy cannula that was resorbed via the tracheostomy lesion.
