Two Cases of the Baboon Syndrome
Abstract
- The baboon syndrome is a type N reaction to systemically administered allergens, which is caused by hematogenous spread of allergens, such as mercury, nickel, ampicillin, amoxicillin, heparin or food additives. Diffuse light-red erythema of the buttocks, upper inner surface of the thighs, and axillae is a distinguishing characteristic of this syndrome. We herein report two cases of the baboon syndrome, which developed after breaking a clinical thermometer. Our patients had a past personal history of contact dermatitis to mercurochrome, and by patch testing were found to have contact allergy to mercury ammonium chloride.
