title: On erythema annulare centrifugum-type of psoriasis.
abstract: A case of EAC type psoriasis is reported. Routine and immunologic investigations were negative. HLA-B8 was found by typing. Some therapeutic benefit was achieved by combination of retinoid (Ro-10-9359) plus PUVA. According to a review of the literature half of the cases are unconnected to classical psoriasis, whereas the other half is connected and mostly of (periodic) pustular character. The necessity of clinical research in this intermediate type between psoriasis vulgaris and pustulosa is emphasized.
