Persistent Erythema Elevatum Diutinum Rarely Resolves Spontaneously

Treatment generally requires targeted measures based on specific etiology and symptoms. Possible causes include genetic factors, environmental stimuli (such as ultraviolet rays or allergens), autoimmune reactions, or underlying chronic conditions; treatment methods may encompass medications (like corticosteroids, antihistamines), phototherapy, or lifestyle adjustments.

1. Possible Causes

Genetic Factors: Some cases of persistent erythema elevatum diutinum may be closely related to genetics, especially among individuals with a family history of skin diseases. Genetics may lead to impaired skin barrier function, making the skin more susceptible to external stimuli and abnormal reactions.
Environmental Stimuli: Long-term exposure to ultraviolet rays, contact with allergens, chemicals, or living in a heavily polluted environment may induce localized chronic inflammation of the skin, leading to persistent erythema.
Autoimmune Issues: Some erythematous lesions may be related to abnormal immune system function, such as lupus erythematosus or dermatomyositis. These autoimmune diseases can cause abnormal dilation of skin capillaries or inflammatory responses.
Pathology or Other Diseases: Persistent erythema elevatum diutinum may be a symptom of certain underlying conditions, such as fungal infections, chronic eczema, or skin cancer.

2. Treatment Suggestions

Medications:
- Topical corticosteroid creams: Such as desonide ointment or halometasone ointment, which can reduce inflammation and alleviate erythema, but long-term use should be under medical supervision to avoid skin thinning.
- Antihistamines: Like loratadine, which have a good effect on improving erythematosus caused by allergies and are suitable for patients with itching symptoms.
- Immunosuppressive drugs: Such as tacrolimus ointment, which can be used for chronic erythematosus caused by immune reasons but requires cautious use after evaluation by a professional physician.
Phototherapy: For erythematosus caused by certain etiologies, ultraviolet phototherapy (such as narrowband UVB) may inhibit skin inflammatory responses. Phototherapy requires evaluation and adaptation symptoms under medical guidance.
Lifestyle Adjustments: Avoid sun exposure and use high-SPF sunscreen when outdoors to prevent chronic skin damage caused by excessive ultraviolet exposure. Stay away from known allergens or chemical irritants, and increase water intake to improve skin barrier function. Dietarily, avoid spicy and stimulating foods, and consume fruits and vegetables rich in antioxidants, such as blueberries and broccoli, to enhance skin repair capabilities.

3. When to Seek Medical Attention

If persistent erythema elevatum diutinum is accompanied by significant itching, pain, or gradually expanding erythema, it is necessary to visit a dermatologist as soon as possible to investigate the etiology. If autoimmune diseases or potential malignant conditions are suspected, further tests such as blood tests and tissue biopsies should be promptly conducted for definitive diagnosis. Persistent erythema elevatum diutinum usually does not resolve spontaneously and should be promptly treated based on the etiology, combined with lifestyle adjustments to improve and control the condition. Regular follow-up is also crucial for long-term management.
