Pustular vasculitic reactions (Q90168)

A clinical reaction pattern characterised clinically by an eruption of multiple small superficial non-follicular sterile pustules, each typically with an erythematous halo surrounding it, and histologically by a vasculitic reaction pattern. It is seen typically as a feature of Behçet disease and as a consequence of exposure to bacterial antigens as in chronic meningococcaemia and gonococcaemia and in the bowel-associated dermatosis-arthritis syndrome.
