Erythema Elevatum Diutinum: Causes, Symptoms, and Diagnosis

Erythema elevatum diutinum (EED) is a rare, chronic skin condition characterized by red or purple bumps that typically appear on the hands, feet, knees, and elbows. This condition is classified as a type of leukocytoclastic vasculitis, which means that it involves inflammation of the small blood vessels in the skin.

Causes:

The exact cause of EED is still unknown. However, it is believed to be associated with several underlying conditions such as autoimmune diseases (e.g., rheumatoid arthritis, lupus), infections (e.g., HIV, hepatitis B), and certain cancers. In some cases, the condition may also be linked to exposure to certain medications or environmental factors.

Symptoms:

The primary symptom of EED is the appearance of firm, red or purple bumps on the affected areas. These bumps can vary in size and may be accompanied by itching or pain. Over time, the bumps may merge together to form plaques or nodules. In rare cases, individuals with EED may also experience joint pain, stiffness, or swelling.

Diagnosis:

Diagnosing EED involves a combination of clinical examination, medical history review, and laboratory tests. A dermatologist will examine the affected skin and may order blood tests to check for underlying conditions. In some cases, a skin biopsy may be performed to confirm the diagnosis.

1. Physical examination: The dermatologist will examine the affected skin areas, noting the appearance and distribution of the bumps.
2. Medical history review: The doctor will ask about the patient's medical history, including any previous skin conditions, autoimmune diseases, or infections.
3. Blood tests: Blood tests may be conducted to check for autoimmune markers or underlying infections.
4. Skin biopsy: A small sample of skin tissue may be taken and examined under a microscope to confirm the diagnosis of EED.

Erythema elevatum diutinum is a rare condition, and its treatment options are limited. However, managing underlying conditions, such as autoimmune diseases or infections, may help alleviate symptoms. It is important to consult with a dermatologist or healthcare professional for proper diagnosis and guidance on managing the condition.
