Allergic contact dermatitis clinical presentation

A retrospective study was performed of 3851 patients who presented at a clinic with suspected allergic contact dermatitis over a 5-year period. Workup of each case included standard patch tests for delayed-type sensitivity. Of the 3851 patients, 145 had type IV allergies to one or more rubber constituents. Five of the 145 were positive to MBT.
