    Case history
    A 56-year-old man presented with chronic plaque psoriasis of eight years duration.

Over the past year he had had a moderate number of plaques affecting particularly his trunk but also his elbows, knees, shins, scalp and glans penis (Figures 1a and b). In some areas, the psoriasis was annular (Figure 1c). He had been taking naproxen 250 mg twice daily for two years for osteoarthritis of his knees; he had no features of inflammatory arthritis. He was moderately obese, drank about eight stubbies of full strength beer weekly and had hypercholesterolaemia controlled with atorvastatin 10 mg daily and diet.
