# Erythema Gyratum Repens Without an Associated Neoplasm: A Rheumatoid Twist

## TL;DR

This paper reports a case of a skin condition typically linked to cancer that instead occurred alongside rheumatoid arthritis.

## Contribution

The study presents a novel case of erythema gyratum repens associated with rheumatoid arthritis rather than cancer.

## Key findings

- Erythema gyratum repens can occur in non-neoplastic contexts.
- The condition was observed in a patient with rheumatoid arthritis.
- This case expands the understanding of EGR beyond its classical paraneoplastic association.

## Abstract

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.
