Systemic allergic dermatitis from chromium in a multivitamin/ multimineral tablet

摘要

We present the first case of systemic allergic dermatitis from chromium chloride in a multivitamin/multimineral tablet that has not been reported previously. A 43-year-old non-atopic lawyer presented with a 10-year history of recurrent vesicular eczema on his hands, wrists, feet, ankles, and lower legs mainly after wearing leather gloves, shoes, or boots. Wearing dark coloured socks worsened his foot eczema. He was aware of no other aggravating factor.Patch testing was performed with the extended European baseline series, and with series of preservatives, emulsifying excipients, fragrances, and leather including leather dyes (Brial Allergen, Greven, Germany) using IQ-Chamber~R (Chemotech-nique Diagnostics, Vellinge, Sweden).
