Erythema gyratum repens
Erythema gyratum repens is associated with internal malignancy in 85% of patients, most commonly lung carcinoma. Other cases have been reported with cancers of the esophagus, breast, cervix, stomach, pharynx, bladder, prostate, uterus, tongue, colon, and pancreas, and anal squamous cell carcinoma. Erythema gyratum repens has also been noted in association with several nonmalignant conditions such as tuberculosis, linear IgA dermatosis, psoriasis, pityriasis rubra pilaris, pemphigus vulgaris, bullous pemphigoid, ichthyosis, and hypereosinophilic syndrome. The male-to-female ratio is 2:1, and the average age of onset is 63 years.
