ReferencesIs e seòrsa de bhroth dearg a th’ ann an Erythema annulare centrifugum (EAC) a tha ann an cumadh fàinne agus a sgaoileas a-mach, a’ fàgail ionad soilleir. Nuair a nochdas EAC air sgàth aillse, canar PEACE (paraneoplastic erythema annulare centrifugum eruption) ris. Tha PEACE nas cumanta ann am boireannaich, gu tric a’ nochdadh mus tèid aillse a dhearbhadh agus is dòcha gun till e às deidh làimhseachadh. Is e EAC aon de na prìomh sheòrsaichean de bhroth ann an cumadh fàinne, le feartan a tha coltach ri prìomh 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 e seòrsa de bhroth dearg a th’ ann an Erythema annulare centrifugum (EAC) a bhios a’ dèanamh cumaidhean cruinn agus gu tric air a bheil craiceann sgàinidh. Thathas den bheachd gu bheil e air a phiobrachadh le diofar fhactaran, ach chan eil sinn cinnteach ciamar a thachras e. Gu cuibheasach, mairidh an bhroth timcheall air 11 mìosan. Bidh sinn a’ bruidhinn air euslainteach aig a bh’ ann an EAC a thàinig air ais airson 50 bliadhna gun adhbhar soilleir. Ged a tha coltas gu bheil e a’ tighinn air ais aig amannan sònraichte san bhliadhna, tha a’ chùis seo a’ riochdachadh an ùine as fhaide a chaidh aithris de Erythema annulare centrifugum (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.

A’ tachairt aig aois sam bith, tha na lòidean sin a’ nochdadh mar fhàinne dearg‑pinc àrdaichte no comharran sùla tairbh. Tha iad eadar meud 0.5‑8 cm (0.20‑3.15 in). Bidh na leòidean uaireannan a’ meudachadh agus a’ sgaoileadh thar ùine, agus ’s dòcha nach eil iad na fhàinneachan iomlan ach cumaidhean neo‑riaghailteach.
Faodar biopsy craicinn a dhèanamh gus an galar a dhearbhadh. Faodaidh na leòidean mairsinn bho àite sam bith le ùine chuibheasach suas ri 11 mìosan. Mar as trice chan eil feum air làimhseachadh, ach dh’fhaodadh steroidan àbhaisteach a bhith cuideachail le lughdachadh deargadh, sèid agus pruine.
