ReferencesErythema annulare centrifugum (EAC) cureyek rîskê sor e ku şêwazê zengilê çêdike û li derve belav dibe, navendek zelal dide. Dema ku EAC ji ber kanserê xuya dike, jê re PEACE (paraneoplastic erythema annulare centrifugum eruption) tê gotin. PEACE di jinan de pir tê dîtin; pir caran berî ku penceşêrê were tespît kirin xuya dike û dibe ku piştî dermankirinê vegere. EAC yek ji wan celêbên sereke yên tîrêjên zengilê e, ku taybetmendiyên bêhempa li gorî erythemasên din ên fîgurê yên mezin (erythema marginatum, erythema migrans, erythema gyratum repens) hene.
Erythema annulare centrifugum (EAC) is an annular, erythematous lesion that appears as urticarial-like papules and enlarges centrifugally, then clears centrally. A fine scale is sometimes present inside the advancing edge, known as a trailing scale. Erythema annulare centrifugum is classified as a reactive erythema and has been associated with various underlying conditions, including malignancies. When erythema annulare centrifugum occurs as a paraneoplastic phenomenon, it has been designated PEACE (paraneoplastic erythema annulare centrifugum eruption). PEACE is more commonly seen in females, typically precedes the clinical diagnosis of malignancy, and may recur with subsequent relapses. EAC is one of the three major figurate erythemas, with EAC being the most common. These dermatoses share the common presentation of advancing erythematous, annular lesions, but are each separated by unique clinical and histopathologic characteristics. Once the other major figurate erythemas (erythema marginatum, erythema migrans, and erythema gyratum repens) are excluded, EAC often becomes a diagnosis of exclusion.

Erythema annulare centrifugum (EAC) cureyek rîskên sor e ku şiklên dordor çêdike û pir caran çermê wê çilmisî ye. Tê fikirîn ku ew ji hêla faktorên cihêreng ve tê rêve kirin, lê em bi rastî nizanin ka ew çawa diqewime. Di navanserê navîn de, raş bi qasî 11 meh berdewam dike. Em li ser nexweşekê ku 50 salî ye, ku EAC bêyî sedemek zelal vedigere, nîqaş dikin. Digel ku ew di hin demên salê de vedigere, ev doz dirêjtrîn raporkirina EAC‑ê temsîl dike.
Erythema annulare centrifugum (EAC) is a type of red rash that forms circular shapes and often has flaky skin. It's thought to be triggered by various factors, but we're not sure exactly how it happens. On average, the rash lasts for about 11 months. We discuss a patient who has had EAC coming back for 50 years without a clear reason. While it does seem to come back at certain times of the year, this case represents the longest reported duration of EAC.

Ev birîn di her demê de xuya dibin; bi taybetî wekî zengila pembe‑sor an jî nîşanên çavê gulan. Mezinahiya wan di navbera 0,5‑8 cm (0,20‑3,15 in) de ye. Carinan birîn mezin dibin, bi demê re belav dibin, û dibe ku ne zengilên tam, lê şekilên nerêkûpêk (irregular) bibin.
Ji bo piştrastkirina nexweşiyê, dikare biopsiya çermê were kirin. Dibe ku birîn li her deverê bi dirêjahiya navînî 11 mehan (months) dom dike. Ew bi gelemperî hewceyê dermankirinê nake, lê dibe ku steroîdên topîk (topical steroids) di kêmkirina sorbûn, werimandin û xuriyê de alîkar bibin.
