Erythema annulare centrifugum
☆ U rezultatima Stiftung Warentest iz Njemačke za 2022., zadovoljstvo potrošača s ModelDermom bilo je samo malo niže nego s plaćenim konzultacijama o telemedicini.
Suprotno ovoj slici, češća je situacija da lezija nema ljuskanje.

ReferencesErythema annulare centrifugum (EAC) je vrsta crvenog osipa koji oblikuje prsten i širi se prema van, ostavljajući jasno središte. Kada se EAC pojavi kao posljedica raka, naziva se PEACE (paraneoplastic erythema annulare centrifugum eruption). PEACE je češći kod žena, često se pojavljuje prije dijagnoze raka i može se vratiti nakon liječenja. EAC je jedan od glavnih tipova osipa u obliku prstena, s jedinstvenim značajkama u usporedbi s drugim velikim figurativnim eritemima (erythema marginatum, erythema migrans i 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 vrsta crvenog osipa koji se pojavljuje u okruglim oblikima i često je praćen perutavom kožom. Smatra se da ga potiču različiti čimbenici, ali točan mehanizam nije poznat. Prosječno, osip traje oko 11 mjeseci. Radi se o pacijentu kod kojeg se EAC ponavlja već 50 godina bez jasnog uzroka. Iako se čini da se pojavljuje u određenom godišnjem dobu, ovaj slučaj predstavlja najduže zabilježeno trajanje EAC‑a.
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.

Bolest se može pojaviti u bilo kojoj dobi, a lezije se pojavljuju kao uzdignuti ružičasto‑crveni prsten ili tragovi nalik bikovima. Veličine su od 0,5 do 8 cm (0,20–3,15 inča). Lezije se ponekad povećavaju i šire tijekom vremena; ne moraju biti potpuni prstenovi, već mogu imati nepravilni oblik.
Za potvrdu bolesti može se napraviti biopsija kože. Lezije mogu trajati različito, s prosječnim trajanjem od 11 mjeseci. Obično ne zahtijeva liječenje, ali lokalni steroidi mogu pomoći u smanjenju crvenila, oticanja i svrbeža.
