Erythema annulare centrifugum (EAC) is an uncommon skin condition characterized by recurring red, ring-shaped (annular) lesions that gradually expand outwards.
Here's a more detailed breakdown:
- Appearance: EAC manifests as small to large, raised, red plaques that form rings on the skin. The rings typically have a slightly raised border and a flatter, less inflamed center.
- Recurrence: The condition is known for its recurring nature, with lesions appearing, resolving, and then reappearing over time.
- Associations: EAC has been linked to various underlying conditions, including:
- Autoimmune disorders
- Infections (bacterial, fungal, viral)
- Neoplastic conditions (cancers)
It's important to note that EAC is a descriptive term, and identifying the underlying cause is crucial for effective management.
