Erythema annulare centrifugum
☆ An den 2022 Stiftung Warentest Resultater aus Däitschland war d'Zefriddenheet vum Konsument mam ModelDerm nëmme liicht manner wéi mat bezuelte Telemedizin Konsultatiounen.
Am Géigesaz zu dësem Bild ass et méi heefeg datt d'Lëftung keng Skaléierung huet.

Erythema annulare centrifugum (EAC) ass eng Aart vu roude Ausschlag, deen eng Ringform formt a sech no baussen verbreet, a léisst e klore Zentrum. Wann EAC erschéngt wéinst Kriibs, ass et PEACE (paraneoplastic erythema annulare centrifugum eruption) genannt. PEACE ass méi heefeg bei Fraen, erschéngt dacks ier Kriibs diagnostizéiert gëtt a kann no der Behandlung zréckkommen. EAC ass eng vun den Haaptarten vu ringfërmege Hautausschlag, mat eenzegaartegen Features am Verglach mat anere grousse Figurate Erythemen (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) ass eng Aart vu roude Ausschlag, déi kreesfërmeg Formen formt an dacks flaache Haut huet. Et gëtt ugeholl datt et vu verschiddene Faktoren ausgeléist gëtt, awer mir sinn net sécher wéi et geschitt. Am Duerchschnëtt dauert den Ausschlag ongeféier 11 Méint. Mir diskutéieren e Patient deen EAC fir 50 Joer zréckkoum ouni kloere Grond. Och wann et schéngt a gewëssen Zäiten vum Joer zréckzekommen, representéiert dëse Fall déi längste gemellt Dauer vun der 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.

Optrieden zu all Alter dës Läsionen erschéngen als opgehuewe rosa-roude Ring oder Bulls-Aen Marken. Si reichen an der Gréisst vun 0,5-8 cm (0,20-3,15 Zoll). D'Läsionen erhéijen heiansdo d'Gréisst a verbreet sech mat der Zäit a kënnen net komplett Réng sinn, awer onregelméisseg Formen.
Eng Hautbiopsie kann ausgefouert ginn fir d'Krankheet ze bestätegen. D'Läsioune kënnen iwwerall daueren mat enger Duerchschnëttsdauer vun 11 Méint. Et erfuerdert normalerweis keng Behandlung, awer topesch Steroiden kënnen hëllefräich sinn fir Rötung, Schwellung an Jucken ze reduzéieren.
