DefinitionThis section has been translated automatically.
Castleman's lymphoma, also Castleman's disease, is a rare systemic disease defined by aetiologically as yet unexplained (HHV-8 infection?) hypertrophy of the lymph nodes with angio-follicular lymphoid hyperplasia.
Two forms of Castleman's lymphoma are distinguished:
- the more frequent localized form (uCD) (about 400 cases have been described worldwide), in which only one lymph node is affected
- the rarer multicentric form (mCD), in which several lymph nodes and lymph node stations are affected. This type is usually associated with HIV infection.

Occurrence/EpidemiologyThis section has been translated automatically.
< 2.4:1000,000/person in the general population.
In HIV-infected patients, the incidence is 4.3 cases per 10,000 patient-years according to a British study.
EtiopathogenesisThis section has been translated automatically.
An essential common feature of Castleman's disease is the overproduction of various cytokines, especially interleukin-6 (IL-6). Thus, the highly variable clinic of mCD is explained by the multiple effects of IL-6 on cells. IL-6 and other proinflammatory cytokines such as IL-10 induce proliferation of B cells and plasma cells, secretion of vascular endothelial growth factors, among others.
In HIV-associated Castleman disease, HHV-8 can be detected 100% of the time. The HHV-8 virus to increased production of a viral interleukin that induces effects similar to human IL-6. IL-6 and IL-10 are elevated in close association with HHV-8 viral load. Viral IL-6, unlike physiological human IL-6, only needs to bind to one of the two IL-6 receptor subunits to exert its effects. In this respect, it has broader leverage at the target cells and is thus likely to cause the disease-causing "cytokine storms" characteristic of HHV-8 MCD.
The pathogenesis of idiopathic mCD is more complex. Possible causes of cytokine overproduction include:
- autoimmune mechanisms
- ectopic secretion of cytokines by malignant cells
- other associated viral infections
- polymorphisms of the interleukin-6 receptor.

Clinical featuresThis section has been translated automatically.
In the localized form, the lymph node regions of the abdomen, subcutaneous lymph nodes and mediastinal lymph nodes are particularly affected. The clinical picture is often defined by fatigue, fever, weight loss and undefinable chest or abdominal pain.
In the multi-centre form of the disease, weight loss (69%), fever (67%), peripheral lymphadenopathy (81%), hepato- and/or splenomegaly (74%) are observed, as well as POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, skin changes - eruptive "senile" angiomas) in about 20% of patients.
Less frequent are uncharacteristic exanthema as well as granulomatous and angiomatous skin manifestations (see glomeruloid hemangioma below) within the framework of the underlying disease.
In individual cases specific infiltrates are also found in the skin.
HistologyThis section has been translated automatically.
Histology: 3 types are distinguished:
- the more frequent hyaline-vascular type: in this type there is an uncontrolled proliferation of a clone of dendritic cells (clonal disease). The structure of the hyaline lymph nodes is "onion-skin-like". This form usually occurs locally.
- The rarer plasma-cell-rich type: this is usually observed in connection with HIV disease. It occurs multifocally and is based on an increased expression of interleukin 6 (IL-6) with a reactive proliferation of plasma cells.
- An intermediate type

Cutaneous and systemic plasmocytosis
Internal therapyThis section has been translated automatically.
Surgical removal: In the localized form of Castleman's disease, complete surgical removal leads to healing in 90% of all cases.
Chemotherapy: CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone)
Alternative: IFN-alpha alone or combined with vinblastine or etoposide
Adjuvant: an anti-IL6 receptor antibody (Siltuximab) may be used. Siltuximab has been approved since 2014 as the first drug for the treatment of idiopathic MCD and has not been tested in HHV-8 MCD because it is unlikely to bind to viral IL-6.
Rituximab: a monoclonal antibody against CD20, has been shown to be effective in HHV-8-MCD in several case series.
Progression/forecastThis section has been translated automatically.
In the localized form of Castleman's disease, complete surgical excision leads to cure in 90% of all cases.
The prognosis of multicentric Castleman's disease is poor. In a study of HIV-infected patients, it averaged only 14 months.
Note(s)This section has been translated automatically.
In the literature, overlaps between the plasma cell type of Castleman's disease and the"cutaneous and systemic plasmocytosis", which occurs preferentially in Asian countries, are discussed.
Castleman's lymphoma is disproportionately associated with paraneoplastic pemphigus.
Angiofollicular lymphoid hyperplasia is not a specific feature of Castleman disease, but is also seen in rheumatoid arthritis, Sjögren's syndrome, and congenital immunodeficiencies . Furthermore, this reaction occurs in malignancies, vaccinations and syphilis.
