Erythema gyratum repens unassociated with underlying malignancy.

A case of erythema gyratum repens occurring in a 62-year-old woman is presented together with a review of the literature. Evaluation and follow-up for the development of malignancy over a 32-month period failed to reveal any evidence of malignancy. Formerly, all cases of erythema gyratum repens were evaluated in terms of an association with an underlying malignant disorder. To date, only sixty cases have been reported in the literature; 14 (23%) were not found to be associated with any neoplasm. Therefore, this term is now also used for cases unassociated with malignancy. Erythema gyratum repens is a cutaneous eruption with a characteristic diagnostic morphology resembling a wood grain pattern.
