What is Castleman Disease?
Castleman Disease is a rare lymphatic disorder that affects the lymph nodes, resulting in abnormal cell growth and dysfunction. Also known as Castleman Syndrome or Castleman lymphadenopathy, this condition is characterized by enlarged lymph nodes and an overactive immune response.
Castleman Disease can occur in two primary forms: unicentric and multicentric. Unicentric Castleman Disease typically involves a single lymph node or a group of lymph nodes in a localized area, while multicentric Castleman Disease affects multiple lymph nodes throughout the body. In some cases, Castleman Disease can also be associated with the human herpesvirus 8 (HHV-8).
This condition is characterized by the excessive production of interleukin-6 (IL-6), a protein that regulates the immune response. Although the exact cause of Castleman Disease is still unknown, it is believed to be related to a combination of genetic and environmental factors.
Key characteristics of Castleman Disease:
- Enlarged lymph nodes
- Excessive production of interleukin-6 (IL-6)
- Overactive immune response
- Potential association with HHV-8
Understanding the key characteristics of Castleman Disease is crucial for early detection and effective management of the condition. In the following sections, we will explore the different types of Castleman Disease, its symptoms, diagnosis, treatment options, and the long-term outlook for individuals affected by this rare disorder.
| Type of Castleman Disease | Description | Key Features |
|---|---|---|
| Unicentric Castleman Disease | Affected lymph nodes localized to a single area | Enlarged lymph nodes, usually non-cancerous |

Types of Castleman Disease
Castleman Disease encompasses several distinct types, each characterized by unique features and manifestations. Understanding these different forms of the disease is essential for accurate diagnosis and treatment. The three main types of Castleman Disease are:
Multicentric Castleman Disease (MCD)
Multicentric Castleman Disease is a systemic lymphoproliferative disorder that affects multiple lymph nodes throughout the body. It is often associated with dysregulated immune system activity and overproduction of certain proteins. MCD can be further divided into two subtypes:
- Idiopathic Multicentric Castleman Disease: This subtype occurs without any known underlying cause and is characterized by the presence of enlarged lymph nodes, flu-like symptoms, and organ dysfunction.
- HHV-8-associated Multicentric Castleman Disease: This subtype is caused by infection with the human herpesvirus 8 (HHV-8). It is more commonly observed in individuals with weakened immune systems, such as those with HIV/AIDS. HHV-8-associated MCD often presents with more severe symptoms and carries a higher risk of complications.
Unicentric Castleman Disease (UCD)
Unicentric Castleman Disease is a localized form of the condition that typically affects a single lymph node or a group of adjacent lymph nodes. Unlike MCD, UCD does not involve widespread lymph node involvement. UCD is often characterized by localized swelling, pain, and other symptoms associated with the affected lymph node.
In some cases, UCD can be treated through surgical removal of the affected lymph node, leading to complete resolution of symptoms.
HHV-8-associated Castleman Disease
HHV-8-associated Castleman Disease is a subtype of multicentric Castleman Disease that is specifically linked to HHV-8 infection. This form of the disease exhibits more aggressive characteristics and carries a higher risk of complications. It is important to note that not all cases of HHV-8 infection progress to HHV-8-associated Castleman Disease.
