[Possible relations between Reiter's disease and psoriasis (author's transl)]

Description of a characteristic venereal type of Reiter's disease with a pustular exanthem and a balanitis circinata. In the course of the disease the pustular exanthem probably transformed into a typical Psoriasis vulgaris. In search of genetical markers it was not possible in this case to show the HLA-antigens, which are characteristic of the Reiter's disease and the Psoriasis vulgaris; the HLA-antigens A 10, B7 and B12 however could be proved. The question is up for discussion, wether a HLA-B 27-negative Reiter's disease might include a disposition to the appearance of a phenotypical Psoriasis vulgaris, the genotype of which is represented by rather "unusual" histocompatibility-gens.
