Figurate erythema is a descriptive term for a skin condition characterized by persistent, erythematous, annular, polycyclic, or serpiginous lesions. The term "figurate" is derived from the Latin word "figura," meaning "figure" or "shape." The condition is often associated with underlying systemic diseases, such as infections, malignancies, and autoimmune diseases.
Causes[edit | edit source]
The exact cause of figurate erythema is unknown. However, it is often associated with underlying systemic diseases. These can include:
- Infections: Certain infections, such as bacterial infections, viral infections, and fungal infections, can trigger figurate erythema.
- Malignancies: Some types of cancer, including lymphoma and leukemia, have been associated with figurate erythema.
- Autoimmune diseases: Conditions such as lupus erythematosus and dermatomyositis can cause figurate erythema.
Symptoms[edit | edit source]
The primary symptom of figurate erythema is the appearance of persistent, erythematous, annular, polycyclic, or serpiginous lesions on the skin. These lesions can vary in size and shape, and they may be itchy or painful.
Diagnosis[edit | edit source]
Diagnosis of figurate erythema is typically based on the characteristic appearance of the skin lesions. Additional tests, such as a skin biopsy, may be performed to confirm the diagnosis and rule out other conditions.
Treatment[edit | edit source]
Treatment for figurate erythema is primarily aimed at managing the symptoms and treating any underlying conditions. This can include:
- Topical corticosteroids: These medications can help reduce inflammation and relieve itching.
- Antihistamines: These can help control itching and reduce inflammation.
- Immunosuppressive drugs: These medications can help control the immune system and reduce inflammation.
