[Psoriasis vulgaris and its relation to atopy].

Psoriasis vulgaris and atopic dermatitis are considered as frequent dermatoses. There are descriptions of possible combination of both diseases when patients with psoriasis vulgaris display signs of atopy or clinical manifestations of atopic dermatitis. We have analysed 9 patients with psoriasis vulgaris and increased levels of IgE. In each case we have found signs of atopy and in one patient also clinical manifestation of atopic dermatitis. Other most frequent immunological markers were represented by increased levels of FW, IgA and C3 component of complement. The combination of psoriasis vulgaris and atopy is possible in one patient but there are many unsolved questions as to the conclusion whether such a case represents a random coincidence or association of both disease.
