I just tripped over an article that cites a patient whose psoriasis 
disappeared on the gluten-free diet. 

De Vos R, "Is there a relationship between psoriasis and coeliac
disease?" _JOURNAL OF INTERNAL MEDICINE_ 1995; 237: 119-123
They go on to test other patients who have psoriasis, and find no elevated
IgA antigliadin antibodies, and conclude that there is likely no 
connection between the two diseases. 

They cite:
Michaelsson G, et al "How common is gluten intolerance among patients with
psoriasis?" _ACTA DERM VENEREOL (Stockh) 1991; 71: 90

indicating that they have seen 7 patients with psoriasis and celiac 
disease, whose psoriasis got better on a gluten-free diet. 

From that I would conclude that psoriasis may be coincidental with celiac
disease, from time to time, but there is no clear relationsip. Nonetheless,
it also appears that psoriasis may be resolved by a gluten-free diet. I 
would sure like to see a clinical trial of that one!
