title: Erythema annulare centrifugum-type psoriasis: a particular variant of acute-eruptive psoriasis.
abstract: A case of erythema annulare centrifugum-type psoriasis in a 58-year-old white woman with a history of chronic plaque psoriasis is described. Initial failure of antipsoriatic treatments and an untypical histology complicated the diagnosis. After several trials acitretin at a low maintenance dose combined with oral fish oil and topical calcitriol led to sustained long-term remission. The spectrum of clinical differentiation of this rare disease, the histological characteristics and its nosological classification are discussed. It is suggested that this dermatosis represents a variant of acute psoriasis, rather than a variant of pustular psoriasis.
