Erythema gyratum repens following COVID-19 infection Dear Editor, Erythema gyratum repens (EGR) is a rare figurate erythema, which presents as annular, erythematous concentric bands resembling wood grain. The diagnosis of EGR is based on clinical findings, supported by histologic findings. Though EGR has been originally reported as a paraneoplastic syndrome, in up to 20–30% of cases, it is associated with nonneoplastic causes, of which 1% are related to infection. We report on a 71-year-old previously healthy (non-smoking) male with the sudden onset of inferior limb pain and paresthesia followed by progressive itchy, erythematous, annular, concentric, slightly scaly patches on the thighs, lower abdomen, and buttocks (Figs. 1 and 2), which started 30 days after a moderately severe COVID-19 infection. Histopathology revealed perivascular lymphocytic infiltrate on the superficial and intermediate dermis, with slight erythrocyte extravasation and eosinophils (Fig. 3).
