Erythema annulare centrifugum
☆ Vo výsledkoch Stiftung Warentest z Nemecka za rok 2022 bola spokojnosť spotrebiteľov s ModelDerm len o niečo nižšia ako s platenými telemedicínskymi konzultáciami.
Na rozdiel od tohto obrázku je bežnejšie, že lézia nemá žiadne škálovanie.

Erythema annulare centrifugum (EAC) je typ červenej vyrážky, ktorá tvorí prstencový tvar a šíri sa smerom von, pričom zanecháva jasný stred. Keď sa EAC objaví v dôsledku rakoviny, nazýva sa PEACE (paraneoplastic erythema annulare centrifugum eruption) . PEACE je bežnejší u žien, často sa objavuje pred diagnostikovaním rakoviny a môže sa vrátiť po liečbe. EAC je jedným z hlavných typov prstencových vyrážok s jedinečnými vlastnosťami v porovnaní s inými veľkými figurálnymi erytémami (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) je typ červenej vyrážky, ktorá tvorí kruhové tvary a má často šupinatú pokožku. Predpokladá sa, že to spúšťajú rôzne faktory, no nie sme si istí, ako presne sa to deje. V priemere vyrážka trvá približne 11 mesiacov. Diskutujeme o pacientovi, u ktorého sa EAC vracia 50 rokov bez jasného dôvodu. Aj keď sa zdá, že sa v určitých obdobiach roka vracia, tento prípad predstavuje najdlhšie hlásené trvanie 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.

Tieto lézie, ktoré sa vyskytujú v akomkoľvek veku, sa javia ako vyvýšené ružovo-červené prstencové alebo býčie stopy. Ich veľkosť sa pohybuje od 0,5 do 8 cm (0,20 až 3,15 palca). Lézie niekedy zväčšujú veľkosť a časom sa šíria a nemusia to byť celé prstence, ale nepravidelné tvary.
Na potvrdenie ochorenia je možné vykonať biopsiu kože. Lézie môžu trvať odkiaľkoľvek s priemerným trvaním 11 mesiacov. Zvyčajne to nevyžaduje liečbu, ale lokálne steroidy môžu byť užitočné pri znižovaní začervenania, opuchu a svrbenia.
