Short answer · Medically reviewed summary · Last updated: 2026-05-08
Castleman disease symptoms are broadly categorized into unicentric (localized) and multicentric (systemic) forms, with the latter often causing severe inflammatory responses such as fever, night sweats, and enlarged lymph nodes. While unicentric Castleman disease is often asymptomatic and discovered incidentally, multicentric Castleman disease requires urgent medical attention due to its potential to affect multiple organ systems simultaneously. What are the most common symptoms of Castleman disease? Symptoms of Castleman disease depend largely on the subtype.
3 people with Castleman disease have shared their first-person experience on this question at DiseaseMaps.
Which are the symptoms of Castleman disease?
Symptoms of Castleman disease reported by real patients, from the most common to the most limiting, plus a medically reviewed summary with sources.
Castleman disease symptoms are broadly categorized into unicentric (localized) and multicentric (systemic) forms, with the latter often causing severe inflammatory responses such as fever, night sweats, and enlarged lymph nodes. While unicentric Castleman disease is often asymptomatic and discovered incidentally, multicentric Castleman disease requires urgent medical attention due to its potential to affect multiple organ systems simultaneously.
What are the most common symptoms of Castleman disease?
Symptoms of Castleman disease depend largely on the subtype. In unicentric cases, patients typically experience a single enlarged, painless lymph node, often in the chest or abdomen. In contrast, multicentric Castleman disease presents with systemic symptoms caused by an overproduction of interleukin-6 (IL-6). Common clinical manifestations include:
- Persistent fevers and night sweats
- Unexplained weight loss and fatigue
- Generalized lymphadenopathy (swollen glands in the neck, armpits, or groin)
- Hepatomegaly or splenomegaly (enlarged liver or spleen)
- Skin rashes or edema (fluid retention)
How does symptom severity vary in patients?
The progression of Castleman disease varies significantly between individuals. Unicentric cases are often benign and resolve with surgical excision of the affected lymph node. However, multicentric Castleman disease is a chronic, life-threatening condition that can lead to organ failure if left untreated. Among the 59 members of the DiseaseMaps.org community living with this condition, reports of "brain fog" and extreme exhaustion are frequently cited as the most impactful factors on daily quality of life.
When should I seek immediate medical attention?
You should seek urgent medical care if you experience rapid onset of high fevers, significant difficulty breathing, or sudden abdominal swelling. These may indicate that Castleman disease is causing systemic inflammation or organ involvement, which requires immediate stabilization by a hematologist or oncologist.
Next steps
- Consult a hematologist-oncologist experienced in rare lymphoproliferative disorders.
- Maintain a symptom diary to track fevers and fatigue patterns for your next appointment.
- Join the DiseaseMaps.org community to connect with other patients and share experiences.
- Discuss potential clinical trials or targeted therapies like anti-IL-6 monoclonal antibodies with your care team.
