Summary
Erythema gyratum repens is a rare skin condition with a distinctive pattern. While often linked to cancer, this case and literature review show it can occur independently of malignancy.
Area of Science:
- Dermatology
- Oncology
Background:
- Erythema gyratum repens (EGR) is a rare, distinctive cutaneous eruption.
- Historically, EGR has been strongly associated with underlying malignant disorders.
Observation:
- A case of EGR in a 62-year-old woman was monitored for 32 months.
- No evidence of malignancy was detected during the follow-up period.
Findings:
- Previously, all EGR cases were presumed to have a neoplastic association.
- Literature review indicates 23% of reported EGR cases (14 out of 60) were unassociated with neoplasm.
- The diagnostic criteria for EGR now include cases without malignancy.
Implications:
- EGR can be a paraneoplastic syndrome or an idiopathic condition.
- This case highlights the importance of thorough evaluation but also acknowledges non-malignant associations.
- Further research may clarify the specific mechanisms and triggers for idiopathic EGR.
