Summary
Erythema gyratum repens, a rare skin condition, can be associated with cutaneous subacute lupus. This case highlights a potential link between these conditions, even without underlying malignancy.
Area of Science:
- Dermatology
- Internal Medicine
- Oncology
Background:
- Erythema gyratum repens (EGR) is a rare, distinctive skin eruption, often linked to internal malignancy.
- Fewer than sixty cases of EGR have been documented in medical literature.
- This report details a unique case involving EGR and cutaneous subacute lupus erythematosus (cSLE).
Observation:
- An 86-year-old woman presented with a two-month history of erythematous patches on her trunk, limbs, and face.
- Skin biopsy results were consistent with cSLE.
- The patient developed characteristic erythematous, concentric, scaly bands on her trunk after initial treatment.
Findings:
- Despite thorough investigation, no internal malignancy was detected.
- The patient's cutaneous lesions resolved with chloroquine and dapsone treatment.
- This case suggests a possible association between EGR and cSLE, independent of malignancy.
Implications:
- EGR may occur in the absence of underlying cancer, as seen in this case.
- The co-occurrence of EGR and cSLE warrants further investigation into potential pathogenetic links.
- This case expands the understanding of EGR's clinical spectrum and its association with autoimmune conditions.
