Erythema gyratum repens is a
The cause is believed to have an immunological base.[4] 80% of cases have an underlying cancer, of which almost half have lung cancer.[1] Sometimes no cause is found.[3]
Diagnosis is generally by its appearance, although tests may be required to exclude other conditions.[3] These tests may include blood tests.[1] A cancer may be located using medical imaging.[1] Necrolytic migratory erythema and erythema migrans are some of many other skin conditions that may appear similar.[1]
Treatment and outlook depend on the underlying cause.[1] Antihistamines may help to reduce the itch.[2][5] The rash typically resolves with successful cancer treatment.[3]
The condition is rare.[1] Males are affected twice as frequently as females.[1] J. A. Gammel first described the condition in 1952.[6][7]

Differential diagnosis
Necrolytic migratory erythema, erythema migrans, tinea corporis, erythrokeratodermia variabilis, and subacute cutaneous lupus erythematosus are some of many other skin conditions that may appear similar.[1]
Treatment
Treatment and outlook depend on the underlying cause.[1] Antihistamines may help to reduce the itch, although the role of applying a steroid cream is unclear.[2][5] The rash typically resolves with successful cancer treatment.[3]
Epidemiology
The condition is rare.[1] Males are affected twice as frequently as females.[1]
History
J. A. Gammel first described the condition in 1952, in an individual who was later found to have breast cancer.[6][7]
