Erythema annulare centrifugum
☆ I 2022 Stiftung Warentest-resultaterne fra Tyskland var forbrugernes tilfredshed med ModelDerm kun lidt lavere end med betalte telemedicinske konsultationer.
I modsætning til dette billede er det mere almindeligt, at læsionen ikke har nogen afskalning.

Erythema annulare centrifugum (EAC) er en type rødt udslæt, der danner en ringform og breder sig udad og efterlader et tydeligt center. Når EAC dukker op på grund af kræft, kaldes det PEACE (paraneoplastic erythema annulare centrifugum eruption) . PEACE er mere almindeligt hos kvinder, optræder ofte før kræft er diagnosticeret og kan komme tilbage efter behandling. EAC er en af hovedtyperne af ringformet udslæt med unikke egenskaber sammenlignet med andre større figurerede erytem (erythema marginatum, erythema migrans, and 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) er en type rødt udslæt, der danner cirkulære former og ofte har skællende hud. Det menes at være udløst af forskellige faktorer, men vi er ikke sikre på præcis, hvordan det sker. I gennemsnit varer udslættet i omkring 11 måneder. Vi diskuterer en patient, der har haft ØK på vej tilbage i 50 år uden en klar grund. Selvom det ser ud til at komme tilbage på bestemte tidspunkter af året, repræsenterer denne sag den længste rapporterede varighed af 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.

Disse læsioner forekommer i enhver alder som hævede pink-røde ring- eller bulls-eye mærker. De varierer i størrelse fra 0,5-8 cm (0,20-3,15 in). Læsionerne øges nogle gange i størrelse og spredes over tid og er muligvis ikke komplette ringe, men uregelmæssige former.
En hudbiopsi kan udføres for at bekræfte sygdommen. Læsionerne kan vare fra hvor som helst med en gennemsnitlig varighed på 11 måneder. Det kræver normalt ikke behandling, men topiske steroider kan være nyttige til at reducere rødme, hævelse og kløe.
