Cu. Brand et al., LYMPHOCYTE-PROLIFERATION ASSAY, A POSSIBL E ALTERNATIVE WAY OF DEMONSTRATING ALLERGIC CONTACT-DERMATITIS IN RESPONSE TO CHLOROACETOPHENONE, Hautarzt, 46(10), 1995, pp. 702-704
We report on a case of pronounced sensitization to chloroacetophenone
tear gas that developed after repeated occupational skin exposure in a
57-year-old police officer. Mainly in the presence of moisture and oc
clusion, cutaneous application of chloroacetophenone leads to severe i
rritant, and often also allergic, skin reactions. In patch testing the
demonstration of allergic contact dermatitis in response to chloroace
tophenone is hampered by the irritative potential of this substance ev
en at low concentrations. This diagnostic bias can be overcome by the
lymphocyte proliferation assay.
