Kaposi Sarcoma-associated herpesvirus (KSHV) KSHV induces B cell hyperplasia and neoplasia such as multicentric Castleman's disease (MCD) and primary effusion lymphoma (PEL). To explore KSHV-induced B cell reprogramming in vivo , we expressed the KSHV latency locus, inclusive of all viral miRNAs, in B cells of transgenic mice in the absence of the inhibitory FcγRIIB receptor. The BALB/c strain was chosen as this is the preferred model to study B cell differentiation. The mice developed hyperglobulinemia, plasmacytosis, and B lymphoid hyperplasia...

Castleman disease is a rare cause of lymphoid hyperplasia and may result in localized symptoms or an aggressive, multisystem disorder. It can mimic other diseases like lymphoma or tuberculosis. It classically presents as a mediastinal mass that involves the lymphatic tissue primarily but can also affect extra lymphatic sites including the lungs, larynx, parotid glands, pancreas, meninges, and muscles. In HIV and HHV8-negative patients with idiopathic multi-centric Castleman disease, pathogenesis may involve autoimmune mechanisms...

Thrombocytopenia, anasarca, fever, renal insufficiency, and organomegaly constitute TAFRO syndrome, a variant of Castleman disease. We describe a patient with TAFRO syndrome who underwent renal biopsy. A 79-year-old woman was referred to us with fever and leg edema. She also had thrombocytopenia, pleural effusion, ascites, and acute kidney injury, and was admitted to our hospital. Her response to initial therapy with corticosteroid and cyclosporine was poor. Therefore, she received 4 doses of rituximab per week, which resulted in clinical improvement, including recovery of thrombocytopenia...

A 67-year-old woman with fever and cough was diagnosed with eosinophilic pneumonia because of eosinophilia and increased eosinophil levels in the bronchoalveolar lavage fluid and transbronchial biopsy lung specimens. However, prednisolone therapy at a previous hospital was ineffective. Histological findings from thoracoscopic lung and lymph node biopsies were consistent with multicentric Castleman's disease (MCD). Since specimens also showed prominent eosinophil and IgG4 -positive plasma cell infiltration, it was difficult to distinguish IgG4 -related disease (IgG4 -RD) from MCD...

Retinoic acid-inducible gene I (RIG-I) is a cytosolic pathogen recognition receptor that initiates the innate immune response against many RNA viruses. We previously showed that RIG-I restricts Kaposi's sarcoma-associated herpesvirus (KSHV) reactivation (J. A. West et al., J Virol 88:5778-5787, 2014, https://doi.org/10.1128/JVI.03226-13). In this study, we report that KSHV stimulates the RIG-I signaling pathway in a RNA polymerase (Pol) III-independent manner and subsequently induces type I interferon (IFN) responses...

Diffuse large B-cell lymphoma (DLBCL) is characterized by medium- to large-sized neoplastic cells that express a wide range of B-cell markers including CD19, CD20, CD22, and CD79a. Also, as this is a hematopoietic malignancy, there is expression of the leukocyte common antigen CD45. Lack of CD20 expression occurs in a specific rare heterogeneous subgroup of DLBCL including primary effusion lymphoma, plasmablastic lymphoma, ALK-positive large B-cell lymphoma, and large B-cell lymphoma arising in HHV8+ multicentric Castleman disease...

Castleman's disease (CD) is a rare benign lymphoproliferative disorder. We are presenting three cases of CD of which one is unicentric CD, and the other two are an idiopathic multicentric CD. One of the two multicentric cases is associated with POEMS syndrome. The whole body 18 F-Fluorodeoxyglucose positron-emission tomography-computed tomography scan plays a significant role in identifying the centricity, distribution of disease, response to therapy, and in early detection of remission.

IgG4-related disease (IgG4-RD) and Castleman's disease (CD) share similar clinical manifestations. When the histopathology coincides with the diagnosis of both IgG4-RD and CD, it is hard to depart the two disease entities utterly; here we call it IgG4-CD provisionally. In this study, we aim to review the clinical features of IgG4-CD. This study is based on a retrospective analysis of a prospectively acquired database. IgG4-CD was defined histopathologically in patients who fulfilled the diagnosis of both IgG4-RD and CD...

Objective: To improve diagnosis and treatment of Castleman' s disease (CD) originating in the head and neck. Method: Of 15 cases of Castleman' s disease originating in the head and neck, 8 cases occurred in the right side of the neck, 6 cases in the left side, and 1 case in both sides. Eleven cases were focal type CD (UCD), and 4 cases were multi-center type CD (MCD). All patients underwent imaging examination and neck nephrectomy. Four patients with MCD received drug treatment after surgery. Result: During follow-up from 12 to 69 months, one patient suffered a slight facial paralysis due to a close relationship between mass and the parotid gland...

Kaposi's sarcoma-associated herpesvirus (KSHV, human herpesvirus 8, or HHV-8) was firstly discovered in Kaposi's sarcoma tissue derived from patients with acquired immune deficiency syndrome. KSHV infection is associated with malignancies and certain inflammatory conditions. In addition to Kaposi's sarcoma, KSHV has been detected in primary effusion lymphoma, KSHV-associated lymphoma, and some cases of multicentric Castleman disease (MCD). Recently, KSHV inflammatory cytokine syndrome (KICS) was also defined as a KSHV-associated disease...

Signal transduction pathways play a key role in the regulation of cell growth, cell differentiation, cell survival, apoptosis, and immune responses. Bacterial and viral pathogens utilize the cell signal pathways by encoding their own proteins or noncoding RNAs to serve their survival and replication in infected cells. Kaposi's sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV-8), is classified as a rhadinovirus in the γ-herpesvirus subfamily and was the eighth human herpesvirus to be discovered from Kaposi's sarcoma specimens...

Kaposi's sarcoma-associated herpesvirus (KSHV), also called human herpesvirus-8 (HHV-8), is the eighth human herpesvirus found by Yuan Chang and Patrick Moore, 1992. It is a Rhadinovirus belonging to the gamma herpesvirus subfamily. As known for many gamma herpesviruses, KSHV is also well-correlated to several cancer formations such as Kaposi's sarcoma, primary effusion lymphoma (PEL), and multicentric Castleman's disease. Different from the other herpesvirus subfamily, gamma herpesviruses establish latency as a default infection strategy when they infect to the target cells, as KSHV is present as the latent form in the related cancers...

Castleman's disease is a distinct form of lymph node hyperplasia. It commonly presents as a mediastinal mass and rarely as a solitary retroperitoneal mass. We narrate a case of Castleman's disease presenting as a right suprarenal mass emphasising the usefulness of robot-assisted retroperitoneoscopy in surgical management of retroperitoneal masses in close relation to vital structures.

RATIONALE: TAFRO syndrome is a systemic inflammatory disorder characterized by thrombocytopenia, anasarca, fever, reticulin fibrosis, renal dysfunction, and organomegaly. In contrast to that in multicentric Castleman disease, interleukin-6 targeting strategies seem ineffective in some TAFRO syndrome cases; however, the optimal treatment remains unclear. Here, we report 2 cases of TAFRO syndrome, where 1 with cardiomyopathy, successfully treated with tacrolimus. This is the first case report of successful treatment with tacrolimus in TAFRO syndrome...

Background: Unicentric mediastinal Castleman disease (CD) is a rare condition, poorly characterized due to the small number of cases and the absence of genomic study. We analyzed clinical, radiological, histological and genomic patterns associated with mediastinal CD in a substantial case series. Methods: We retrospectively reviewed cases of unicentric mediastinal CD managed in 2 French thoracic surgery departments between 1988 and 2012. Clinical, radiological, surgical and pathological data were recorded...

Castleman disease is a lymphoproliferative disorder with unknown etiology and pathogenesis. While the disease may involve all parts of the body, the mediastinum appears to be the most common part of involvement. In this study, we present two cases of Castleman disease with different localizations that mimicked malignancy. A 62-year-old female patient presented with jaundice. Laboratory analysis indicated aspartate aminotransferase: 250 U/L, total bilirubin: 4 mg/dl, and carbohydrate antigen (CA) 19-9: 900 U/ml...
