Dithranol allergy: fact or fiction?
A case of a psoriatic patient allergic to dithranol and coal tar is described. It is suggested that dithranol 0.001% pet. is a suitable concentration to test for dithranol allergy, as higher concentrations may produce irritant reactions. The literature on dithranol allergy is reviewed and the frequent simultaneous reactions to dithranol and coal tar discussed.
