Abstract:
Occupational allergic contact dermatitis from metallic mercury is rare. Here we present the only 2 patients with relevant occupational mercury allergy detected at our clinic since 1974. The first patient was a dental nurse who became sensitized to metallic mercury from amalgam when handling uncured amalgam without protective gloves. The second patient had previously been sensitized to mercury from topical medicaments and developed work-related dermatitis when a mercury thermometer was broken at her place of work. Both patients had a positive patch test reaction to metallic mercury.
