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.

“…Acitretin 139 , dapsone 138, 140, 141 , and methotrexate have been successful in patients requiring systemic therapy. Low-dose methotrexate has been used with success in the pediatric setting 105 .…”

Erythema anulare centrifugum Darier

“…Differenzialdiagnostisch muss an eine Tinea corporis oder einen subakut kutanen Lupus erythematodes sowie an eine anuläre bzw. gyrierte Psoriasis vulgaris gedacht werden [5,8]. Zum Ausschluss von Triggerfaktoren sollte eine Fokussuche mit entsprechender Sanierung im Vordergrund stehen.…”

“…Obwohl eine Erythema-anulare-centrifugum-artige, gyrierte Psoriasis vulgaris existiert [8], konnte diese histologisch in unserem Fall ausgeschlossen werden.…”
