title: Erythema gyratum repens with associated squamous cell carcinoma of the lung.
abstract: A 63-year-old man with erythema gyratum repens (EGR) was found to have an underlying squamous cell carcinoma of the lung. Neither radiation nor chemotherapy had any effect on the extensive eruption. EGR is the most distinctive of the figurate erythemas, and continues to be one of the most consistent cutaneous signs of an associated visceral malignancy.
