Angiofollicular lymph node hyperplasia, also known as Castleman disease, is a rare medical condition that affects the lymph nodes in your body. In this article, we’ll break down the types of Castleman disease, its potential causes, common symptoms, diagnostic tests, treatment options, and medications used to manage the condition.

Types of Castleman Disease

There are two main types of Castleman disease:

1. Unicentric Castleman Disease (UCD):
   • UCD involves a single group of enlarged lymph nodes in one specific area of the body, such as the neck or chest. It’s typically not as severe as the multicentric form.
2. Multicentric Castleman Disease (MCD):
   • MCD affects multiple groups of lymph nodes throughout the body, which can lead to more widespread symptoms. It is often associated with infections like HIV or herpes.

Potential Causes of Castleman Disease:

The exact cause of Castleman disease is not well-understood, but several factors may contribute to its development. These include:

1. Viral Infections: Some viral infections, like HIV and herpes, may trigger multicentric Castleman disease in susceptible individuals.
2. Immune System Dysfunction: An overactive immune system may play a role in the development of Castleman disease.
3. Genetic Predisposition: Some genetic factors may increase the risk of developing the condition.
4. Inflammation: Chronic inflammation may contribute to Castleman disease in some cases.
5. Environmental Factors: Exposure to certain environmental toxins or substances may be a risk factor.
6. Age: Castleman disease can occur at any age, but it’s more common in young adults.
7. Gender: It appears to affect both males and females equally.
8. Autoimmune Disorders: People with autoimmune disorders may have a higher risk.
9. Hormonal Factors: Hormonal imbalances could be linked to Castleman disease.
10. Medications: Some medications may be associated with an increased risk.
11. Infections: Certain bacterial or viral infections may trigger the disease.
12. Inflammatory Diseases: Conditions like rheumatoid arthritis or lupus may be linked.
13. Chemical Exposures: Exposure to specific chemicals may contribute to Castleman disease.
14. Allergies: Severe allergies might play a role.
15. Stress: High levels of stress may affect the immune system.
16. Diet: Dietary factors could influence the risk.
17. Alcohol and Tobacco Use: These habits might be risk factors.
18. Heredity: A family history of Castleman disease may increase the risk.
19. Autoimmune Response: An abnormal immune response may be involved.
20. Unknown Factors: In some cases, the cause remains unknown.

Diagnostic Tests for Castleman Disease:

Diagnosing Castleman disease involves various medical tests, including:

1. Physical Examination: A doctor will check for swollen lymph nodes and other symptoms.
2. Blood Tests: These can detect abnormal blood cell counts or markers of inflammation.
3. Imaging Scans: CT scans or MRI scans can show enlarged lymph nodes and affected organs.
4. Biopsy: A tissue sample from a lymph node is examined under a microscope to confirm the diagnosis.
5. Lymph Node Removal: In some cases, a lymph node may be surgically removed for analysis.
6. Bone Marrow Biopsy: This helps determine if the disease has spread to the bone marrow.
7. Lymph Node Aspiration: A needle is used to extract fluid or cells from a lymph node.
8. PET Scan: It can identify areas of active inflammation.
9. HIV Testing: For cases associated with HIV.
10. Herpes Testing: For cases linked to herpes infections.
11. Liver Function Tests: To assess liver involvement.
12. Kidney Function Tests: To check for kidney problems.
13. Pulmonary Function Tests: If lung involvement is suspected.
14. Eye Examination: For ocular symptoms.
15. Electromyography (EMG): If neuropathy is suspected.
16. Skin Biopsy: For skin-related symptoms.
17. Endoscopy: To examine the digestive tract if needed.
18. Chest X-ray: For lung-related symptoms.
19. Electrocardiogram (ECG): To assess heart function.
20. Ultrasound: To examine specific organs or areas.

Treatment Options for Castleman Disease:

Treatment for Castleman disease depends on its type and severity. Here are some common approaches:

1. Watchful Waiting: In some cases, especially with unicentric Castleman disease, no treatment may be necessary, and the condition is monitored over time.
2. Surgery: Surgical removal of the affected lymph nodes may be performed for unicentric Castleman disease.
3. Radiation Therapy: High-energy X-rays target affected lymph nodes.
