Erythema annulare centrifugum: An Overview

Erythema annulare centrifugum (EAC) is a rare skin condition characterized by red, circular or annular rashes that spread outwards from the center. While the exact cause of EAC remains unknown, it is commonly associated with underlying systemic conditions, such as infections, autoimmune disorders, medications, or malignancies.

Here are some key points to know about Erythema annulare centrifugum:

1. Appearance: EAC typically presents as raised, pink or red rings with a clear center. The outer edge of the rash may be slightly elevated and have a scaly or blister-like texture. The lesions are usually symmetrical and can vary in size from a few millimeters to several centimeters.
2. Location: EAC lesions commonly occur on the trunk, buttocks, thighs, and arms. In some cases, they may also appear on the palms, soles of the feet, or face.
3. Symptoms: The rash associated with EAC is usually asymptomatic or mildly itchy. It may persist for weeks or months, with individual lesions fading away while new ones emerge at the periphery.
4. Diagnosis: A dermatologist can diagnose EAC by visually examining the rash and considering the patient's medical history. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other potential causes.
5. Treatment: While this article does not cover treatment, it's important to note that EAC does not require specific therapy in most cases. The condition is typically self-limiting, resolving spontaneously over time. However, if an underlying cause is identified, addressing that condition may help alleviate EAC symptoms.

It is crucial to consult a healthcare professional if you suspect you have Erythema annulare centrifugum or any other skin condition. They can provide an accurate diagnosis and appropriate guidance based on your specific situation.

In conclusion, Erythema annulare centrifugum is a unique skin condition characterized by circular, expanding rashes. While the cause remains unknown, it is often associated with underlying systemic conditions. If you notice any concerning symptoms, seek medical advice promptly for an accurate diagnosis and appropriate management.
