J Thormann, and N B Jespersen, and H D Joensen

Forty-eight patients with a positive patch test to potassium dichromate 0.5% were retested after 4-7 years; 38 patients (79%) still had a positive patch test. Chromate allergy seems to be persistent. In 72% of the cases a history of occupational exposure to chromates could be proved.
