Papular dermatitis and a persistent patch test reaction to gold sodium thiosulfate.

Abstract

The role of gold in allergic contact dermatitis is poorly understood and is a subject of increasing interest. Recent studies demonstrate that gold-positive patch testing is not uncommon, but persistent patch test reactions are rarely reported. We present a case of a 53-year-old woman with a 7-year history of a scattered, pruritic papular dermatitis. Patch testing demonstrated a persistent, positive reaction to gold sodium thiosulfate. The histopathology of the patch test site and that of the cutaneous eruption were similar in nature but differing in severity. No other allergens have been identified, but gold avoidance has not yet resulted in the clearing of her eruption. This case underscores the difficulty in making a clinical correlation despite suggestive clinical pathologic evidence.
