Erythema gyratum repens: a paraneoplastic eruption.

Abstract

Erythema gyratum reopens is a slowly expanding, mildly scaling dermatosis with a "wood-grain" pattern and is seen in patients with an underlying malignancy. To date only 49 cases have appeared in the literature, 41 of which (84%) were associated with a neoplasm, most commonly of the lung. Several patients also had pruritus, palmoplantar keratoderma, ichthyosis, vesiculobullous lesions, and/or eosinophilia. Histopathologic findings are nonspecific. The skin findings usually disappear with therapy for the underlying malignancy.
