Erythema Gyratum Repens Without an Associated Neoplasm: A Rheumatoid Twist

Erythema gyratum repens (EGR) is a distinctive dermatosis characterized by multiple, annular, rapidly migrating erythematous plaques with multiple concentric rings, producing a wood-grain-like pattern. Although classically described as a paraneoplastic marker, it is no longer regarded as an obligate paraneoplastic syndrome, as a growing number of cases without associated malignancy have been reported. We present a case of EGR occurring in association with rheumatoid arthritis (RA), highlighting its occurrence in a non-neoplastic context.
