Patch testing in psoriasis patients: results of a 30-year retrospective study

Abstract

Psoriasis and allergic contact dermatitis (ACD) are common, chronic T-lymphocyte mediated conditions. Although psoriasis patients are commonly referred for patch testing, there are conflicting views on the relationship between contact allergy and psoriasis. Previous studies have suggested ACD is less common in psoriasis¹ and that psoriatics are more difficult to sensitize^1,2,3.
