Some data on frequency and nature of occupational dermatological diseases and stigmata, as well as the results of epicutaneous allergy tests done with occupational allergens with 234 rollers in the rolling mills of the aluminum mill in Razine, near Sibenik are presented. We have recorded occupational dermatose in 44 rollers (18.8%). In the hot rolling mill, sixty rollers have undergone the test and there was 16 recorded cases of occupational dermatose (26.6%). In the cold rolling mill, 174 rollers have undergone the test, and the occupational dematose was recorded in 28 rollers (16.1%). Positive epicutaneous allergic reaction on occupational allergens was found in 5 (2.1%) rollers. Occupational stigmata are somewhat more frequent in the hot rolling mill and their ratio is from 48-100%, whereas in the cold rolling mill they are somewhat less frequent ranging between 40.3 and 97.0% of rollers.
