Erythema annulare centrifugum
☆ Í niðurstöðum Stiftung Warentest 2022 frá Þýskalandi var ánægja neytenda með ModelDerm aðeins minni en með greiddum fjarlækningaráðgjöfum.
Öfugt við þessa mynd er algengara að sárið sé ekki með neina flögnun.

Erythema annulare centrifugum (EAC) er tegund af rauðum útbrotum sem myndar hringlaga lögun og dreifist út og skilur eftir sig skýra miðju. Þegar EAC kemur fram vegna krabbameins er það kallað PEACE (paraneoplastic erythema annulare centrifugum eruption) . PEACE er algengara hjá konum, kemur oft fram áður en krabbamein er greint og gæti komið aftur eftir meðferð. EAC er ein af helstu gerðum hringlaga útbrota, með einstaka eiginleika miðað við önnur helstu fígúrulaga roða (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) er tegund rauðra útbrota sem mynda hringlaga form og eru oft með flagnandi húð. Talið er að það sé komið af stað af ýmsum þáttum, en við erum ekki viss nákvæmlega hvernig það gerist. Að meðaltali varir útbrotin í um 11 mánuði. Við ræðum sjúkling sem hefur fengið EAC að koma aftur í 50 ár án skýrrar ástæðu. Þó að það virðist koma aftur á ákveðnum tímum ársins, þá táknar þetta mál lengsta tilkynnta tímalengd 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.

Á hvaða aldri sem er, birtast þessar meinsemdir sem upphækkaðir bleikrauður hringir eða augnamerki. Stærðir þeirra eru á bilinu 0,5–8 cm (0,20–3,15 tommur). Skemmdirnar aukast stundum og dreifast með tímanum og eru kannski ekki heilir hringir heldur óregluleg lögun.
Hægt er að framkvæma húðsýni til að staðfesta sjúkdóminn. Skemmdirnar geta varað hvar sem er með að meðaltali 11 mánuði. Það þarf venjulega ekki meðferð, en staðbundnir sterar geta verið gagnlegar til að draga úr roða, bólgu og kláða.
