ReferencesKo Erythema annulare centrifugum (EAC) he momo ponana whero e hanga ana i ngā mowhiti, ka horapa ki waho, ā, ka noho marama te pokapū. Inā puta te EAC i te mate pukupuku, ka kīia ko PEACE (paraneoplastic erythema annulare centrifugum eruption). He nui ake te pānga o PEACE ki ngā wāhine; he maha ngā wā ka puta i mua i te kitenga o te mate pukupuku, ā, ka hoki mai anō i muri i te maimoatanga. Ko te EAC tētahi o ngā momo tino āhua o te whakakai, ā, ka whakatauritea ki ētahi atu erythemas nui (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.

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.
