Erythema annulare centrifugum
☆ I dtorthaí 2022 Stiftung Warentest ón nGearmáin, ní raibh sástacht na dtomhaltóirí le ModelDerm ach beagán níos ísle ná mar a bhí le comhairliúchán teileamhíochaine íoctha.
Murab ionann agus an pictiúr seo, tá sé níos coitianta go bhfuil an lesion gan aon scálú.

Is cineál gríos dearg é Erythema annulare centrifugum (EAC) a dhéanann cruth fáinne agus a leathnaíonn amach, ag fágáil lárionad soiléir. Nuair a thagann an chuma ar EAC mar gheall ar ailse, tugtar PEACE (paraneoplastic erythema annulare centrifugum eruption) air. Tá PEACE níos coitianta i measc na mban, is minic a thagann sé chun solais sula ndéantar diagnóis ailse agus d'fhéadfadh sé teacht ar ais tar éis cóireála. Tá EAC ar cheann de na príomhchineálacha rashes fáinne-chruthach, le gnéithe uathúla i gcomparáid le mór-erythemas figurate eile (erythema marginatum, erythema migrans, erythema gyratum repens) .
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.

Is cineál gríos dearg é Erythema annulare centrifugum (EAC) a fhoirmíonn cruthanna ciorclach agus go minic bíonn craiceann calógach air. Ceaptar go bhfuil sé spreagtha ag fachtóirí éagsúla, ach nílimid cinnte go díreach conas a tharlaíonn sé. Ar an meán, maireann an gríos ar feadh thart ar 11 mhí. Pléimid othar a raibh EAC ag teacht ar ais ar feadh 50 bliain gan chúis shoiléir. Cé gur cosúil go dtagann sé ar ais ag amanna áirithe den bhliain, léiríonn an cás seo an t-achar ama is faide a thuairiscítear don EAC.
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.

Tarlaíonn na loit seo ag aois ar bith mar mharcanna fáinne bándearg-dearg ardaithe nó marcanna súl tairbh. Réimsíonn siad i méid ó 0.5-8 cm (0.20-3.15 in). Uaireanta méadaíonn na loit méid agus scaipeann siad le himeacht ama agus b'fhéidir nach fáinní iomlána iad ach cruthanna neamhrialta.
Is féidir bithóipse craiceann a dhéanamh chun an galar a dhearbhú. Féadfaidh na loit maireachtáil ó áit ar bith le meánré 11 mhí. De ghnáth ní bhíonn cóireáil ag teastáil uaidh, ach d’fhéadfadh stéaróidigh tráthúla a bheith ina chuidiú chun deargadh, at agus cos a laghdú.
