Erythema gyratum repens
Erythema gyratum repens (pronunciation: eh-RITH-eh-muh JY-ruh-tum REH-penz) is a rare dermatological condition characterized by concentric, erythematous bands that migrate across the skin. The term is derived from the Greek words "erythema" meaning redness, "gyratum" meaning circular, and "repens" meaning creeping.
Definition
Erythema gyratum repens is a paraneoplastic cutaneous syndrome, meaning it is a skin disorder associated with underlying malignancies. It is characterized by the rapid progression of erythematous, concentric, serpiginous bands that give the skin a wood-grain appearance.
Symptoms
The primary symptom of Erythema gyratum repens is the presence of migrating, concentric, erythematous bands on the skin. These bands often have a trailing scale, and they typically migrate at a rate of 1 cm per day. Other symptoms may include pruritus (itching) and, in some cases, the presence of an underlying malignancy.
Causes
The exact cause of Erythema gyratum repens is unknown, but it is most commonly associated with underlying malignancies, particularly lung cancer and esophageal cancer. It has also been associated with other types of cancer, including breast cancer, stomach cancer, and colon cancer.
Diagnosis
Diagnosis of Erythema gyratum repens is primarily based on the characteristic appearance of the skin lesions. A skin biopsy may be performed to confirm the diagnosis. Additionally, due to the strong association with underlying malignancies, a thorough investigation for cancer is typically undertaken when this condition is diagnosed.
Treatment
Treatment of Erythema gyratum repens primarily involves addressing the underlying malignancy. In some cases, topical or systemic corticosteroids may be used to manage symptoms.
