Castleman disease is a rare disorder that involves an overgrowth (proliferation) of cells in your body's disease-fighting network (lymphatic system). Also known as giant lymph node hyperplasia and angiofollicular lymph node hyperplasia, Castleman disease can occur in a localized (unicentric) or widespread (multicentric) form.
Fever. Night sweats. Fatigue and weakness. Loss of appetite. Unintended weight loss. Enlarged lymph nodes, usually around the neck, collarbone, underarm and groin areas. Enlarged liver or spleen.
HIV MCD has been shown to be associated with infection with human herpervirus-8 (HHV8). Vascular endothelial growth factor and the cytokine interleukin-6 (IL-6) are also thought to play a role in the pathogenesis of MCD. Currently, rituximab is often used alone or in combination with chemotherapy for treatment of MCD. Novel monoclonal antibodies targeting IL-6 and the IL-6 receptor are also being studied for the management of this disease.
