Abstract
Growth and immune process dysregulation can result in both cancer and nonmalignant disease (hereditary or acquired, with and without predisposition to malignancy). Moreover, perhaps unexpectedly, many nonmalignant illnesses harbor genomic alterations indistinguishable from druggable oncogenic drivers. Therefore, targeted compounds used successfully to treat cancer may have therapeutic potential for nonmalignant conditions harboring the same target. MEK, PI3K/AKT/mTOR, fibroblast growth factor receptor (FGFR), and NRG1/ERBB pathway genes have all been implicated in both cancer and noncancerous conditions, and several cognate antagonists, as well as Bruton's tyrosine kinase inhibitors, JAK inhibitors, and CD20-directed antibodies, have established or theoretical therapeutic potential to bridge cancer and benign diseases. Intriguingly, pharmacologically tractable cancer drivers characterize a wide spectrum of disorders without malignant potential, including but not limited to Alzheimer's disease and a variety of other neurodegenerative conditions, rheumatoid arthritis, achondroplastic dwarfism, and endometriosis. Expanded repositioning of oncology agents in order to benefit benign but serious medical illnesses is warranted.

[PMID: 38791038 PMCID: PMC11118735 DOI: 10.3390/biomedicines12051076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 05/04/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024] Open
Abstract
TAFRO syndrome is a rare and aggressive inflammatory entity characterized by thrombocytopenia, anasarca, fever, renal failure, reticulin fibrosis, and organomegaly. This entity supposes a diagnostic and therapeutic challenge due to its significant overlap with Castleman's disease. However, distinct clinical and histological features warrant its classification as a separate subtype of idiopathic multicentric Castleman's disease (iMCD). While recent modifications have been made to the diagnostic criteria for iMCD, these criteria lack specificity for this particular condition, further complicating diagnosis. Due to its inflammatory nature, several complex molecular signaling pathways are involved, including the JAK-STAT pathway, NF-kB, and signal amplifiers such as IL-6 and VEGF. Understanding the involvement of immune dysfunction, some infectious agents, genetic mutations, and specific molecular and signaling pathways could improve the knowledge and management of the condition, leading to effective treatment strategies. The current therapeutic approaches include corticosteroids, anti-IL6 drugs, rituximab, and chemotherapy, among others, but response rates vary, highlighting the need for personalized strategies. The prognosis is uncertain due to diagnostic difficulties, emphasizing the importance of early intervention and appropriate targeted treatment. This comprehensive review examines the evolving landscape of TAFRO syndrome, including the pathophysiology, diagnostic criteria, treatment strategies, prognosis, and future perspectives.

Abstract
OBJECTIVES This paper presents an Australian model that formed part of the health technology assessment for public investment in siltuximab for the rare condition of idiopathic Multicentric Castleman Disease (iMCD) in Australia. METHODS Two literature reviews were conducted to identify the appropriate comparator and model structure. Survival gain based on available clinical trial data were modelled using an Excel-based model semi-Markov model including time-varying transition probabilities, an adjustment for trial crossover and long-term data. A 20-year horizon was taken, and an Australian healthcare system perspective was adopted, with both benefits and costs discounted at 5%. The model was informed with an inclusive stakeholder approach that included a review of the model by an independent economist, Australian clinical expert opinion and feedback from the Pharmaceutical Benefits Advisory Committee (PBAC). The price used in the economic evaluation reflects a confidential discounted price, which was agreed to with the PBAC. RESULTS An incremental cost-effectiveness ratio of A$84,935 per quality-adjusted life-year (QALY) gained was estimated. At a willingness-to-pay threshold of A$100,000 per QALY, siltuximab has a 72.1% probability of being cost-effective compared with placebo and best supportive care. Sensitivity analyses results were most sensitive to the length of interval between administrations (from 3- to 6-weekly) and crossover adjustments. CONCLUSION Within a collaborative and inclusive stakeholder framework, the model submitted to the Australian PBAC found siltuximab to be cost-effective for the treatment of iMCD.

Abstract
Thrombocytopenia, anasarca, fever, reticulin fibrosis/renal failure, and organomegaly (TAFRO) syndrome is rare in clinical practice. It is a systemic inflammatory disease caused by a cytokine storm. Its clinical manifestations include thrombocytopenia, systemic edema, fever, bone marrow fibrosis, renal insufficiency, and organ enlargement. The high mortality rate of TAFRO syndrome is due to the difficulty of acquiring biopsy samples for diagnosis and the rapid disease progression. This disease is poorly understood by clinicians. Early detection, accurate diagnosis, and timely treatment play key roles in prolonging the survival of the patients. This review summarizes the latest progress in the pathogenesis, diagnostic criteria, and treatment regimens of TAFRO syndrome, aiming to help clinicians better understand TAFRO syndrome and improve its diagnosis and treatment.

Abstract
Castleman disease (CD) is a group of rare and complex lymphoproliferative disorders that can manifest in two general forms: unicentric CD (UCD) and multicentric CD (MCD). These two forms differ in clinical manifestation, imaging appearances, treatment options, and prognosis. UCD typically manifests as a solitary enlarging mass that is discovered incidentally or after development of compression-type symptoms. MCD usually manifests acutely with systemic symptoms including fever and weight loss. As a whole, CD involves lymph nodes throughout the chest, neck, abdomen, pelvis, and axilla and can have a wide variety of imaging appearances. Most commonly, lymph nodes or masses in UCD occur in the chest, classically with well-defined borders, hyperenhancement, and possible characteristic patterns of calcification and/or feeding vessels. Lymph nodes affected by MCD, while also hyperenhancing, tend to involve multiple nodal chains and manifest alongside anasarca or hepatosplenomegaly. The polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes (POEMS) subtype of MCD may demonstrate lytic or sclerotic osseous lesions in addition to features typical of MCD. Since a diagnosis of CD based solely on imaging findings is often not possible, pathologic confirmation with core needle biopsy and/or surgical excision is necessary. Nevertheless, imaging plays a crucial role in supporting the diagnosis of CD, guiding appropriate regions for biopsy, and excluding other potential causes or mimics of disease. CT is frequently the initial imaging technique used in evaluating potential CD. MRI and PET play important roles in thoroughly evaluating the disease and determining its extent, especially the MCD form. Complete surgical excision is typically curative for UCD. MCD usually requires systemic therapy. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Abstract
Abstract
Castleman’s disease is a benign lymphoproliferative disorder. The coexistence of Hodgkin’s lymphoma and multicentric Castle-man’s disease is a rare phenomenon. We discuss a case of a 48-year-old female patient who had been in the records of the Colentina Hematology Clinic since 2019, with the diagnosis of classic Hodgkin’s Lymphoma, nodular sclerosis type I BNLI, stage IIXB. For this, she underwent 3 courses of ABVD and 2 courses of BEACOPP, without showing complete remission on PET/CT evaluation at the end of treatment. After that, we initiated rescue therapy and performed 4 IGEV courses, followed by autologous stem cell transplantation. For maintenance treatment, we opted for Brentuximab, but it was discontinued after the first administration due to the appearance of adverse reactions. Subsequently, we decided to perform radiotherapy with 20 fractions cumulating a total dose of 36 Gy. Shortly after the radiotherapy, symptoms reappeared which were suspected to be in the context of a relapse of the disease. For confirmatory diagnosis, we performed a new PET-CT which highlighted metabolically active ganglion images. Further, were carried out lymph node biopsy for histopathological and immunohistochemical examinations were carried out. The underlying disease was diagnosed as plasmacytic subtype, HHV8 negative, multicentric Castleman’s disease. For treatment, we relied on administrations of Siltuximab treatment therapy that showed complete remission. Castleman’s disease presents a unique diagnostic challenge, but a confirmatory diagnosis can be based on a biopsy examination, advisable after each relapse.

Abstract
Castleman disease (CD) is a rare lymphoproliferative disorder. The mechanistic target of rapamycin (mTOR) pathway is a key regulator of various cellular functions, which may be related with the potential mechanisms of CD occurrence. We retrospectively collected the clinical information of 60 CD patients diagnosed in the First Affiliated Hospital of Zhengzhou University. And FFPE biopsy specimens were collected from 31 patients (12 unicentric CD patients and 19 multicentric CD patients) to detect the mTOR pathway protein expression. We are the first to demonstrate that thrombocytopenia and hypoalbuminemia are independent poor prognostic factors for CD. Moreover, mTOR activation was higher in CD compared to reactive lymphoid hyperplasia (used as a control group). This study offers some elucidation for the management and treatment of CD patients.

Abstract
Castleman disease (CD) is a rare lymphoproliferative disorder with distinct clinical subtypes. However, our understanding of the underlying pathogenesis of particular subtypes of CD remains unclear. While the characteristic morphologic changes within UCD, including occasional cases of overgrowth of spindled stromal and follicular dendritic cells have been described, the nature and origin of these spindle cells remain elusive. Few reports have suggested that underlying stromal cells in UCD are clonally neoplastic and may be of fibroblastic reticular cell (FRC) or follicular dendritic cell (FDC) origins given their close clonal relationship. Although certain histomorphologic features may aid diagnosis, there are no specific biomarkers that can differentiate a reactive process mimicking UCD from true UCD. Hence, we describe an index case with morphology consistent with the hyaline vascular subtype of UCD with concomitant atypical smooth muscle actin (SMA)-positive stromal spindle cell proliferation containing a recurrent PDGFRB N666S mutation and upregulation of p53 expression. Further analysis of 21 additional cases of UCD identified increased p53 expression by digital image analysis and SMA positive stromal cells predominantly within the paracortical and intrafollicular areas further strengthening the hypothesis of the stromal cellular derivation and origins of UCD.

Abstract
Castleman Disease (CD) is a rare entity that typically presents as an enhancing nodal mass in the mediastinum or head and neck region on computed tomography (CT). It may manifest as unicentric or multicentric regions of lymph node enlargement. A key clinical issue in the context of CD is delayed diagnosis, which contributes adversely to patient outcome, given that accurate diagnosis facilitates earlier treatment of this curable disease. This article will address relevant imaging aspects, with reference to typical and atypical imaging features of CD, illustrated using examples from our specialist centre; the imaging journey for patients with CD; and will provide practical pointers to radiologists in differentiating CD from other benign and malignant causes of enhancing lymphadenopathy, including lymphoma and neoplastic adenopathy. We will also review current classification tools and staging challenges with reference to World Health Organization guidelines, International Working Group guidelines as well as the Lugano classification. Finally, we will discuss the potential role of additional imaging techniques in CD, highlighting novel imaging methods and expanded utilities from our specialist centre.

Abstract
The immune system plays a key role in cancer prevention, initiation, and progression. Antitumoral immune responses can be boosted by harnessing antitumorigenic immune activators and/or blocking tumorigenic proinflammatory factors. Here we define these targets as well as the strategies that could be developed for effective cancer immunoprevention.

Abstract
ABSTRACT Castleman disease (CD) is a poorly understood lymphoproliferative disorder characterized by enlarged lymph nodes. The spectrum of differential diagnoses is wide, and it is hard to differentiate from other diseases. Cutaneous involvement of CD is rare, and studies that describe cutaneous dermatopathology of CD are scarce. The aim of this study was to collect case reports of CD with cutaneous manifestations and identify potential relevant histopathological features. We found that cases of CD with cutaneous manifestations often exhibited dermal lymphoid follicles with follicle center infiltration of lymphocytes and plasma cells. These dermal follicles also had regressive or atrophic germinal centers and were penetrated by hyalinized vessels. Patients with CD also consistently exhibited perivascular and deep dermal inflammatory infiltrate, primarily composed of lymphocytes and plasma cells. We intend to raise awareness of this rare entity and provide more histopathological information regarding its dermatological manifestations.

Abstract
Castleman disease is a complex benign lymphoproliferative disorder characterized by the enlargement of a single lymph node or a group of lymph nodes. Its etiology is unclear, with the mechanism of action of IL-6 and HHV-8 implicated as possibly associated with the development of the disease. Diagnosis depends on the histopathological findings of the involved lymph nodes. Surgical resection can be curative, but a small number of cases may be unresectable and need radiation and chemotherapy with subsequent resection if possible.

Abstract
OBJECTIVES Castleman disease (CD) is a heterogeneous group of disorders involving systemic inflammation and lymphoproliferation. Recently, clonal mutations have been identified in unicentric CD (UCD) and idiopathic multicentric CD (iMCD), suggesting a potential underlying neoplastic process. METHODS Patients with UCD or iMCD with next generation sequencing (NGS) data on tissue DNA and/or circulating tumor DNA (ctDNA) were included. RESULTS Five patients were included, 4 with iMCD and 1 with UCD. Four patients (80%) were women; median age was 40 years. Three of five patients (60%) had ≥1 clonal mutation detected on biopsy among the genes included in the panel. One patient with iMCD had a 14q32-1p35 rearrangement and a der(1)dup(1)(q42q21)del(1)(q42) (1q21 being IL-6R locus) on karyotype. This patient also had a NF1 K2459fs alteration on ctDNA (0.3%). Another patient with iMCD had a KDM5C Q836* mutation, and one patient with UCD had a TNS3-ALK fusion but no ALK expression by immunohistochemistry. CONCLUSIONS We report 4 novel somatic alterations found in patients with UCD or iMCD. The 1q21 locus contains IL-6R, and duplication of this locus may increase IL-6 expression. These findings suggest that a clonal process may be responsible for the inflammatory phenotype in some patients with UCD and iMCD.

Abstract
Objective: To investigate the long-term clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with human herpes virus 8 (HHV8)-positive multicentric Castleman’s disease (MCD). Methods: A 17-year-old female patient was admitted to Henan Provincial People’s Hospital with the complaint of febrile for half a month, headache, and enlarged superficial lymph nodes on October 5, 2010. HHV8-positive mixed cellular Castleman’s disease was found by pathological diagnosis of lymph nodes biopsy. After the administration of CHOP and Hyper-CVAD-B, the patient was still febrile, we administrated the followed COAP, two courses of VAD(Vincristine, Adriamycin, Dexamethasone), the patient received CR. Six months after CR, the patient relapsed, we administrated VAD and two courses of bortezomide+dexamethasone chemotherapy, and then the patient received PR. After that, the patient underwent allo-HSCT from his human leukocyte antigen (HLA)-matched unrelated donor after conditioning with Bu/Cy+Etoposide+Smoustin.graft-vs-host disease (GVHD) prophylaxis, which consisted of ATG (7.5 mg/kg, qd, ivdrip) from d-5 to d-2, cyclosporine (3 mg/kg/d, qd, ivdrip, for 24 h) started from day-1, MMF(0.5 g, tid, po.) started from day+1 to +28, and MTX (15 mg per time, ivdrip, d+1,+4,+7,+11). She received 3.5×106/L CD34+cells and 8.1×108/LMNC. Results: Granulocyte engraftment occurred on day+12, platelet engrafted on day+14. Bone marrow biopsy showed normalization of trilineage hematopoiesis on day+33, chimerism: 97.6%. The transplantation was successful and followed up for 7 years with CR. Conclusion: Allo-HSCT might cure patients with refractory/relapsed HHV8+ MCD.

Abstract
Our aim was to investigate the usefulness of 18fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in the diagnosis, treatment response evaluation, and follow-up of human herpesvirus-8 (HHV-8)-associated multicentric Castleman’s disease (MCD). Fifteen patients with histologically diagnosis of HHV-8-associated MCD were retrospectively included. For all patients, a 18F-FDG PET/CT scan was performed before any treatment for diagnosis and PET/CT scans after Rituximab (4 cycles) for the evaluation of treatment response; moreover, 22 PET/CT were performed during the follow-up to check disease status. To evaluate treatment response, we applied Deauville criteria. PET/CT findings were compared with other conventional imaging (CI) findings. At diagnosis, 18F-FDG PET/CT showed an increased FDG-uptake in all cases corresponding to lymph nodes and confirming the MCD. The average SUVmax of the FDG avid lesions were 8.75, average lesion-to-liver SUVmax ratio was 3.6, and average lesion-to-blood pool SUVmax ratio was 3.9. After first-line therapy, 18F-FDG PET/CT resulted negative (Deauville score < 4) in seven patients and positive in the remaining eight (Deauville score 4–5). A negative restaging PET/CT was associated with a lower risk of relapse. During follow-up, PET/CT detected the presence of relapse or progression in 5 (23%) cases with an accuracy higher than CI. 18F-FDG PET/CT seems to be an useful tool in studying HHV-8-associated MCD both at diagnosis and during follow-up.

Abstract
TAFRO syndrome is an extremely rare form of idiopathic MCD, characterized by thrombocytopenia, anasarca, fever, reticulin fibrosis on bone marrow biopsy, and organomegaly. Like idiopathic MCD, renal involvement is also a common presentation in patients with TAFRO syndrome. Furthermore, membranoproliferative glomerulonephritis (MPGN)-like injury and thrombotic microangiopathy (TMA) are the most reported histopathologic findings of renal biopsy. Several molecular mechanisms have been previously postulated in order to explain the TAFRO syndrome symptoms, including abnormal production of interleukin-6 (IL-6), vascular endothelial growth factor (VEGF), etc. The role of these cytokines in renal injury, however, is not well understood. The aim of this review article is to summarize the latest knowledge of molecular mechanisms behind the TAFRO syndrome and their potential role in renal damage.

Abstract
Introduction and importance Castleman's disease was first reported by Benjamin Castleman et al., in 1954 and described it as a sporadic lymphoproliferative disorder. The pathophysiology to this day is still unknown, although IL-6 is suspected to play an important role. Preoperative diagnosis is challenging due to its non-specific symptoms, and that imaging cannot clearly distinguish the disease from other processes. High clinical awareness is necessary to reach a diagnosis. If the disease is localized, complete recovery can be achieved through surgery. Case presentation Patient is a 68-year-old woman with a three-month history of recurrent episodes of fever, myalgias, and night sweats. She started to experience lower abdominal pain and presented to the emergency room. A contrast-enhanced abdominal computed tomography revealed a 5 cm well-circumscribed focal heterogeneously enhancing hyperplastic mass between the portal vein and the inferior vena cava. After successful laparoscopic surgery, the mass was resected, and the patient fully recovered. Unicentric Castleman's disease was the final diagnosis. Discussion and conclusion Castleman's disease is an uncommon pathology with a challenging diagnosis. When approaching an abdominal mass, unicentric Castleman's disease should always be a differential diagnosis, as treatment can be curative with surgical resection. With the advent of laparoscopic and robotic surgery, these techniques can improve patients' outcomes in these rare pathologies, especially when they appear in complex regions. Castleman's disease is an uncommon pathology with a challenging diagnosis. Abdominal Unicentric Castleman's disease must be considered when approaching a patient with an abdominal mass. Surgery is the most effective treatment for Unicentric Castleman's disease, and with laparoscopy, better results are expected.

Abstract
Castleman's disease is a rare disease characterized by benign lymphoepithelial proliferation. There are two forms: unicentric and multicentric Castleman's disease. Mediastinal location is the most frequent. Intra-abdominal Castleman's disease is a rare presentation. We report a case of 65-year-old female who presented with epigastric pain. Investigations revealed a retroperitoneal mass which was surgically resected. Histopathological examination showed hyaline-vascular type Castleman's disease. In conclusion, Castelman´s disease is a diagnostic challenge and it must be included in the differential diagnosis of retroperitoneal tumors.

Abstract
Castleman disease (CD) describes a group of rare hematologic conditions involving lymphadenopathy with characteristic histopathology and a spectrum of clinical abnormalities. CD is divided into localized or unicentric CD (UCD) and multicentric CD (MCD) by imaging. MCD is further divided based on etiological driver into human herpesvirus-8-associated MCD, POEMS-associated MCD, and idiopathic MCD. There is notable heterogeneity across MCD, but increased level of pro-inflammatory cytokines, particularly interleukin-6, is an established disease driver in a portion of patients. FDG-PET/CT can help determine UCD versus MCD, evaluate for neoplastic conditions that can mimic MCD clinico-pathologically, and monitor therapy responses. CD requires more robust characterization, earlier diagnosis, and an accurate tool for both monitoring and treatment response evaluation; FDG-PET/CT is particularly suited for this. Moving forward, future prospective studies should further characterize the use of FDG-PET/CT in CD and specifically explore the utility of global disease assessment and dual time point imaging.

Abstract
OBJECTIVE. The purpose of this article is to review important imaging and clinical features to help elucidate causes of lymphadenopathy in patients with HIV infection. CONCLUSION. HIV lymphadenopathy has various causes generally categorized as inflammatory or reactive, such as immune reconstitution syndrome; infectious, such as tuberculous and nontuberculous mycobacterial infections and HIV infection itself; and neoplastic, such as lymphoma, Kaposi sarcoma, and Castleman disease. It is important to consider patients' demographic characteristics, clinical presentations, CD4 lymphocyte counts, and radiologic features to identify likely causes of lymphadenopathy.

Abstract
Background Idiopathic multicentric Castleman disease (iMCD) is an uncommon lymphoproliferative disorder and lacks treatment consensus. Herein, we report a case of iMCD complicated with Sjögren’s syndrome (SS) and secondary membranous nephropathy (SMN). Case presentation A 45-year-old female with dry mouth for 3 months and anasarca and proteinuria for 2 months was admitted. She also experienced chest tightness, wheezing, fever, weight loss, moderate proteinuria and hypoalbuminemia. A computed tomography (CT) scan revealed a tissue mass in the thymus area and enlarged multiple lymph nodes. Her symptoms did not improve after resection of the thymus mass. The pathological findings were “reactive hyperplasia of the mediastinal lymph nodes and thymic hyperplasia”. Lymph node biopsy findings confirmed iMCD with human herpes virus-8 (HHV-8) negativity. Based on anti-nuclear antibody (ANA) 1:320, anti-SSA and anti-SSB antibody positivity, salivary flow less than 0.1 ml/min and lip biopsy with focal lymphocytic sialadenitis, SS was diagnosed. Kidney biopsy showed secondary membranous nephropathy with endocapillary cell proliferation and infiltration of plasma cells and lymphocytes in the tubulointerstitium. Serum interleukin-6 (IL-6) levels were significantly increased, and therapy with tocilizumab (anti-IL-6 receptor antibody) worked well. The combination of cyclophosphamide (CyS) with methylprednisolone (MP) maintained satisfactory remission. Conclusions Our case of iMCD with SS and SMN is rare. There is a need for increased awareness of the disease to avoid unnecessary procedures and misdiagnoses. IL-6 was extremely high, and there was a rapid response to anti-IL-6 receptor agents. The combination of CyS with MP maintained complete remission.

Diagnostics (Basel) 2020; 10:diagnostics10120998. [PMID: 33255420 PMCID: PMC7761046 DOI: 10.3390/diagnostics10120998] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Revised: 11/20/2020] [Accepted: 11/21/2020] [Indexed: 01/09/2023] Open
Abstract
Castleman disease (CD) is a relatively rare lymphoproliferative disorder and the pathophysiology of the subtypes are incompletely understood. Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) demonstrates the metabolic activity of inflammatory and tumorous conditions. The FDG uptake intensity and sites of involved lesions on FDG PET/CT were assessed by histologic subtypes, and compared to the patient's hemoglobin, platelet, albumin, and high-sensitivity C-reactive protein (hs-CRP) levels. In total, 60 PET/CT images of 44 consecutive CD patients were included: 4 (9%) unicentric and 40 (91%) multicentric; 21 (48%) hyaline vascular subtype, 16 (36%) plasma cell, and 7 (16%) mixed or unclassified. The maximum standardized uptake value (SUVmax) and tumor-to-liver (T/L) ratio of involved lymph nodes (LNs) were 5.3 ± 2.4 (range, 1.6-11.5) and 2.8 ± 1.6 (range, 1.1-9.6), respectively, with no significant difference between the histologic subtypes. Higher number of involved LN stations and presence of extra-nodal involvement on FDG PET/CT were associated with thrombocytopenia, hypoalbuminemia, and elevated hs-CRP levels (p values < 0.05). FDG-avidity was not different by histologic subtypes and did not correlate with laboratory findings. However, the extent of nodal and extra-nodal involvement as noted on FDG PET/CT was significantly associated with abnormal laboratory findings in patients with CD.

Abstract
Objective: To investigate the clinicopathologic features, treatment, and prognosis in patients with Castleman disease (CD) . Methods: We retrospectively analyzed the clinicopathologic data of 59 patients for whom a diagnosis of Castleman disease was confirmed using pathological examination from October 2011 to October 2019 at the Henan Cancer Hospital. The patients were divided into the following two groups as per the following clinical classifications: unicentric CD (UCD, n=47) and multicentric CD (MCD, n=12) . Data on clinical manifestations, laboratory findings, treatment, and prognosis were analyzed. Results: There was no significant difference in the median age and the ratio of male to female between the UCD and MCD. UCD was characterized by asymptomatic enlargement of the single lymph node. The main pathological type was hyaline vascular histopathology (83.0%) . Of these, 44 patients chose surgical resection, and their prognosis was good. Treatment. MCD was characterized by multiple enlarged superficial and/or deep lymph nodes with B symptoms, weakness, and hepatosplenomegaly. Anemia, hypoproteinemia, and globulin level were increased on laboratory examinations. Plasmacyte histopathology was the main pathological type and was present in about 50.0% of the subjects. Only chemotherapy was performed for these MCD patients, followed by chemotherapy or chemotherapy followed by radiotherapy, and the efficient was 58.3% (7/12) . Conclusions: UCD, characterized by asymptomatic enlargement of the single lymph node, shows good postoperative prognosis. MCD has relatively complex clinical manifestations and poor prognosis, and optimal treatment is yet to be established.

Abstract
Background Castleman disease (CD) is a rare lymphoproliferative disease characterized by high heterogeneity in clinical manifestation and prognosis. This study aimed to summarize clinical features of localized retroperitoneal CD and our experiences to improve the diagnosis and treatment of this disease. Methods Clinical data of 45 patients with localized retroperitoneal CD were retrospectively analyzed. The differences in clinical features between groups with and without paraneoplastic pemphigus (PNP) were compared. Survival was analyzed between groups depending on whether complicating with PNP, bronchiolitis obliterans (BO), gender, age and uni-centric CD (UCD)/multi-centric CD (MCD), respectively. Results Significant differences were observed between patient groups in the prevalence of retroperitoneal CD with PNP complicated with BO (P=0.010), the constituent ratios of initial symptoms (P<0.001) and the duration from appearance of the initial symptoms to being diagnosed (P=0.009). Among 45 cases, 43 tumors had clear margins and intact envelops and were completely resected, 40 patients were cured or significantly relieved, 3 patients were not significantly relieved, 2 patients received palliative surgical therapy and eventually relapsed and died after surgery. There were significant differences in the survival rate between groups depending on complication with BO, gender and age (≤40 and >40 years) (all P<0.05). Conclusions Prompt and complete removal of the retroperitoneal CD tumor is critical to the management of this disease, as palliative resection tends to cause relapse and lead to a poor prognosis. Retroperitoneal CD patients with PNP may develop complications from BO leading to death. Complication with PNP, complication with BO, male gender and age ≥40 years were identified as prognostic risk factors for patients with localized retroperitoneal CD.

Abstract
Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is a pandemic with major implications across the world. One of the most frequent causes of death from SARS-CoV-2 is fatal pneumonia from coronavirus disease 2019 (COVID-19), which is associated with the development of acute respiratory distress syndrome (ARDS). To date (as of April 2, 2020), other than supportive measures, there are no efficient therapeutic options for COVID-19-related ARDS, although the US Food and Drug Administration recently granted emergency authorization for the use of hydroxychoroquine/chloroquine for this indication (which is usually given with azithromycin). Although the pathogenesis for ARDS is under investigation, one of the major culprits is considered to be cytokine storm, especially from interleukin 6 (IL-6) release. Herein, we review potential use of IL-6 inhibitors, several of which are approved for other disease conditions, as potential novel treatment for the management of COVID-19-related ARDS.

Abstract
INTRODUCTION Castleman's disease (CD) is a rare disorder characterized by benign angio follicular lymphoid hyperplasia, with gentle behavior. Its etiology and prevalence are unclear. It is usually found in the mediastinal area and it is rare to see this tumor in the retroperitoneum. PRESENTATION OF CASE A 53 year old male with a retroperitoneal hypervascular calcified mass densely adherent to the psoas muscle that was accidentally encountered on a CT scan. Provisional diagnosis of retroperitoneal liposarcoma was made and the patient underwent an exploratory laparotomy. The histologic examination of the surgically resected specimen disclosed « a hyaline type of Castleman's disease ». DISCUSSION Castleman's disease, is a rare heterogenous group of lymphoproliferative disorders that arises mostly in the mediastinum. The retroperitoneal localization is very rare. Clinically, CD can be subdivided into a localized form (unicentric disease) and a generalized form (multicentric disease) according to the number of lymph nodes involved. A careful histological and immunohistochemical examination of the tumor tissue after surgery is the only way for tumor diagnosis. CONCLUSION Castelman's disease is a rare entity that has often benign and non invasive behavior, but remains a diagnostic challenge. There is no reliable diagnostic method and its definitive diagnosis is based on histopathology report. For treating the unicentric variant, radical surgical resection is considered to be the gold standard.

Abstract
PURPOSE To characterize the effects of disease type and clinical characteristics on the pharmacokinetics of siltuximab, an IL-6 inhibiting monoclonal antibody. METHODS Siltuximab pharmacokinetic data were combined from seven phase I/II clinical trials. A population pharmacokinetic model was developed to characterize changes in siltuximab disposition with disease type, albumin, liver and renal function, and patient demographics. RESULTS A total of 7761 concentrations from 460 participants were used in the study. The data were well described by a two-compartment model. Castleman's disease, healthy volunteer status, albumin, and ALT were independent predictors of clearance. Monte Carlo simulations of the final model for an 11 mg/kg dose resulted in a longer median half-life for healthy volunteers (24.5 days) as compared to Castleman's disease (19.1 days) and other tumor types (22.2 days). Clearance varied 1.8-fold over the range of albumin values seen in the study (1.5-5.2 g/dL), while ALT resulted in minimal changes in clearance. CONCLUSIONS Albumin and disease state are important factors for siltuximab disposition and will likely need to be considered for dosing in future therapeutic applications.

Abstract
Multicentric Castleman disease (MCD) is a rare lymphoproliferative disorder with a high mortality rate in undiagnosed patients. Traditionally, human immunodeficiency virus (HIV) positive MCD occurs due to infection with human herpes virus-8 (HHV), which is thought to play a role in the pathogenesis of MCD. We present the case of a 49-year-old woman who was referred to our oncology clinic for generalized lymphadenopathy in a waxing and waning pattern for the last four years. She was found to be HIV positive. Here we report a rare case of HIV-positive, HHV-negative MCD that responded to prompt treatment with highly active antiretroviral therapy (HAART) followed by chemotherapy as evidenced by improved CD4+ T cell numbers and reduction in lymphadenopathy. The findings in this HHV seronegative patient may indicate an alteration in the virulence and tropism between HHV and HIV, and further demonstrate the need for continued investigation into the pathogenesis of Castleman disease.

Abstract
BACKGROUND Castleman disease (CD) is an uncommon lymphoproliferative disorder that is rare in pediatric populations; the literature describing this population is sparse. We sought to describe pediatric CD, including unicentric CD (UCD) and human herpes virus-8 (HHV8)-negative multicentric CD (MCD), in a multi-institutional cohort. METHODS We retrospectively reviewed 24 patients, aged 0 to 26 years at diagnosis, who were diagnosed with CD between January 1, 2005, and May 16, 2017, at two tertiary children's hospitals. Demographic and clinical data were collected. RESULTS Most patients (75%, 18/24) presented with UCD. All patients with MCD were HHV8-negative. The most common histopathologic variant was hyaline vascular (75%, 18/24). Plasma cell variant occurred in 33% (2/6 [95% confidence intervals (CI), 4-78%]) of patients with HHV8-negative MCD and 17% (3/18 [95% CI, 4-41%]) of patients with UCD. Systemic symptoms were present in 4 of 6 of patients with HHV8-negative MCD and 8 of 18 of patients with UCD. Anemia and laboratory inflammation occurred in both UCD and MCD patients, with nonsignificantly higher rates of anemia and elevated C-reactive protein in MCD patients. All but two UCD patients underwent gross total resection as definitive therapy. Among HHV8-negative MCD patients, a combination of resection, chemotherapy, and immunotherapy was used. No UCD patients and three of six HHV8-negative MCD patients experienced disease progression/relapse prior to lasting remission. There were no deaths. CONCLUSION Pediatric patients with CD most commonly have unicentric, hyaline vascular variant disease. Pediatric patients with both UCD and MCD commonly have systemic inflammation and, despite risk of progression/relapse in MCD patients, ultimately have excellent survival.

BACKGROUND Castleman disease (CD) is a rare lymphoproliferative disorder that presents with various symptoms. CD accompanied with jaundice is uncommon since there are only 11 cases reported in the literature.
CASE SUMMARY Here we report a 62-year-old woman who was admitted to the hospital with signs and symptoms of intermittent jaundice. Biochemical tests showed higher serum levels of total and direct bilirubin, and normal serum levels of tumor markers and interleukin-6. Contrast-enhanced computed tomography detected a 6 cm × 4 cm × 2.5 cm mass between the hepatoduodenal ligament and the inferior vena cava. The mass was successfully excised and the patient had a complete resolution of symptoms. A diagnosis of idiopathic unicentric CD was made based upon histological examination, which demonstrated the pathological features of CD of mixed type, including hyperplasia of follicular lymphoids with abundant plasma cells, degenerative germinal centers, interfollicular vascularity and hyaline degeneration. The diagnosis was corroborated by immunohistochemical analysis which detected multiple biomarkers.
CONCLUSION This is the first study that describes the clinicopathological features of CD presenting with jaundice, which may deepen and extend our understanding of this disease.

Abstract
Chronic basophilic leukemia (CBL) is an extremely rare type of leukemia. A literature review revealed six cases reported as primary CBL and five patients with secondary CBL. Patients with primary CBL may present with symptoms not related to leukemia. Dysplastic changes in peripheral blood and bone marrow were described and demonstrated in cases of primary and secondary CBL. The literature review also revealed that differential counts made by automated blood cell counters may not characterize cells as basophils in patients with primary and secondary CBL and may mislead physicians in making a differential diagnosis. For these reasons, laboratory studies for the diagnosis of CBL are required, including metachromatic staining by toluidine blue and antigen expressions by flow cytometric analysis, to detect the nature of the neoplastic cells as basophils for a reliable diagnosis of CBL. The literature review failed to reveal specific cytogenetic findings in patients with primary and secondary types of CBL.

Abstract
Castleman's disease (CD) is a rare lymphoproliferative disease with unclear pathogenesis. CD is divided into unicentric and multicentric according to clinical classification, and is usually successfully treated with surgical resection alone. CD is also classified into hyaline vascular, plasma cell, or mixed cell type according to histopathological type. CD can occur in any part of the lymphatic tissue, but most occur in mediastinal lymph node, followed by the neck, armpit, and abdominal lymph nodes. Here, we have reported a case of Castleman disease which was accidently discovered during the operation of common bile duct calculi. The histological presentation of the lymph nodes was corresponded to the plasma cell type of CD. To our knowledge, there is no report about the plasma cell type of Castleman's disease coexistence with common bile duct calculi. Finally we also review the literature.

Abstract
Castleman disease: heterogeneous group of hyperimmune lymphoproliferative disorders. Unicentric type: localized disease; surgery is primary treatment; good prognosis. Multicentric type: Serious systemic disease; 70% linked to HHV8; antiviral therapy. Idiopathic Multicentric type: diagnosis by exclusion; Interleukin-6 blockade useful.
Castleman Disease (CD) is a rare, heterogeneous group of hyperimmune lymphoproliferative disorders, not very familiar to surgeons. Unicentric Castleman Disease (UCCD) at one end of the spectrum is a localized disease, with little or no systemic symptoms. It may be an incidental radiological finding or detected while investigating for a symptomatic lymph node mass. Surgery is the primary treatment and has good long term prognosis. Multicentric Castleman Disease (MCCD) is a more serious systemic condition, often associated with constitutional symptoms. Exaggerated systemic inflammatory response secondary to “Cytokine storm” involving Interleukin-6 (IL-6) may cause multi-organ dysfunction. In addition, immunosuppression or malignant transformation can prove lethal. Human Herpes Simplex Virus 8 (HHV8) associated MCCD is a major subgroup occurring in immunocompromised individuals due to the viral trigger. Antiviral therapy is important in its treatment. Idiopathic MCCD (IMCCD) has no known biomarker and is diagnosed after excluding infective, autoimmune and malignant conditions of lymphoid tissue. IMCCD requires systemic therapy. We report a patient of UCCD who presented as a retroperitoneal mass in right iliac fossa causing pressure on femoral nerve. Following successful surgical excision she had good recovery. We report another patient who had large inguinal lymph node mass with constitutional symptoms. IMCCD was diagnosed after excision biopsy and comprehensive work up. Patient was started on corticosteroids followed by CD-20 targeted therapy. These two cases showcase the two ends of the clinical spectrum of CD requiring different management protocols. Awareness among surgeons and diligent work-up is imperative for early diagnosis and best outcome.

Abstract
Patients with HHV-8-negative/idiopathic multicentric Castleman disease (iMCD) experience systemic inflammatory symptoms and polyclonal lymphoproliferation due to an unknown etiology. Schnitzler's syndrome (SS) is characterized by recurrent urticarial rash, monoclonal IgM gammopathy, and other clinical signs of inflammation. To our knowledge, we report the first case of iMCD associated with SS and the fourth case of anakinra inducing a complete response for an iMCD patient. A forty-four year old woman with a history of a recurrent urticarial rash, presented to our hospital complaining of 6 months of night sweats, fever, chronic urticaria, iliac bone pain, and generalized lymphadenopathy. An IgM Kappa monoclonal component was measured at 7.8g/L. A lymph node biopsy revealed histopathological features consistent with the plasma cell variant of iMCD. She was diagnosed with SS and iMCD. Anti-IL-1 treatment with anakinra (100mg/day) was introduced. Within 48h, we observed improvement in the fever and the urticarial rash. By one month, we considered the patient in complete remission. Two years later, the remission is persistent while the patient is still under therapy. Though this is only the fourth reported case of anakinra in iMCD, this is yet another case demonstrating the effectiveness of anti-IL-1 blockade in SS. We hypothesize that uncontrolled cytokine production is responsible for both the SS and the iMCD. The etiologies of SS and iMCD are unknown, and future research is necessary.

Abstract
Human Herpesvirus-8 (HHV-8)-negative/idiopathic multicentric Castleman disease (iMCD) is a poorly understood disease involving polyclonal lymphoproliferation with dysmorphic germinal centers, constitutional symptoms, and multi-organ failure. Patients can experience thrombocytopenia, anasarca, reticulin fibrosis, renal dysfunction, organomegaly, and normal immunoglobulin levels, - iMCD-TAFRO. Others experience thrombocytosis, milder effusions, and hypergammaglobulinemia, -iMCD-Not Otherwise Specified (iMCD-NOS). Though the etiology is unknown in both subtypes, iMCD symptoms and disease progression are believed to be driven by a cytokine storm, often including interleukin-6 (IL-6). However, approximately two-thirds of patients do not respond to anti-IL-6 therapy; alternative drivers and signaling pathways are not known for anti-IL-6 nonresponders. To identify potential mediators of iMCD pathogenesis, we quantified 1129 proteins in 13 plasma samples from six iMCD patients during flare and remission. The acute phase reactant NPS-PLA2 was the only significantly increased protein (P = .017); chemokines and complement were significantly enriched pathways. Chemokines represented the greatest proportion of upregulated cytokines, suggesting that iMCD involves a chemokine storm. The chemokine CXCL13, which is essential in homing B cells to germinal centers, was the most upregulated cytokine across all patients (log2 fold-change = 3.22). Expression of CXCL13 was also significantly increased in iMCD lymph node germinal centers compared to controls in a stromal meshwork pattern. We observed distinct proteomic profiles between the two iMCD-TAFRO patients, who both failed anti-IL-6-therapy, and the four iMCD-NOS patients, in whom all three treated with anti-IL-6-therapy responded, suggesting that differing mechanisms may exist. This study reveals proteomic differences between flare and remission and the potential to molecularly define iMCD subgroups.

Abstract
Multicentric Castleman disease (MCD) is a rare nonmalignant lymphoproliferative disorder presenting systemic symptoms such as fever, night sweats, fatigue, anemia, effusions, and multifocal lymphadenopathy. The etiology of MCD has not been clarified to date. The coexistence of MCD with chronic myelomonocytic leukemia (CMML) has been rarely reported. Although the pathogenesis remains unclear, this association probably reflects an incidental and fortuitous finding rather than the alteration of a common pluripotent stem cell precursor. Herein, we report on one case of MCD coexisting with CMML and elucidate the underlying mechanism of pathology in some aspects.

Abstract
Background Our case describe a rare recurrence case of Unicentric Castleman’s disease (UCD) with hyaline vascular type 14 years after surgery. Case presentation A 35-year-old Chinese female was admitted to hospital with one and half months history chest distress and chest pain. Patient reports a history of thoracic operation for mediastinal mass 14 years ago, and it was diagnosed UCD with hyaline vascular type after postoperative pathological examination. At this time, the imaging examination showed a mediastinal mass once again. Combining the medical history, postoperative microscopically examination and immunoperoxidase staining, patient was again diagnosed UCD with hyaline vascular type again. The hyaline vascular type is the most common type and usually presents as a UCD. Most patients with UCD have no clinical symptoms. The diagnosis of UCD is generally achieved with histological and immunohidtochemical findings postoperatively. Currently, the standard treatment of UCD is the complete surgical resection, with almost no relapse postoperative. The recurrence in UCD with hyaline vascular type postoperative have not previously been reported. Therefore, herein we describe a recurrence case of UCD with hyaline vascular type 14 years after surgery. Conclusion Our case is the first case which reports the relapse of UCD with hyaline vascular type after completely surgery. It indicates that long term follow-up is necessary for patient who is diagnosed UCD after surgery.

Abstract
The aim of the present study was to share the experience of a single institute in the diagnosis, use of accessory examinations and treatment strategies of Castleman's disease (CD). The present study analyzed 34 patients (13 males and 21 females) with CD who were hospitalized between January 2006 and September 2014. The patients were divided into two groups based on the anatomical distribution of the disease: Unicentric CD (UCD) and multicentric CD (MCD). Histological data was obtained from lymph node biopsies. All clinical data were acquired by reviewing patients' medical records and contacting patients by telephone. A total of 27 patients had UCD and 7 patients had MCD. All 27 patients with UCD with benign symptoms underwent complete diagnostic surgical resection and survived, with the exception of 1 patient who succumbed to pancreatic head carcinoma 13 months after surgery. A total of 7 patients with MCD presented with systemic symptoms and 2 of these patients declined treatment following the definite diagnosis of CD. The remaining 5 patients were treated with various strategies, including surgical resection and further glucocorticoid treatment, intravenous siltuximab, rituximab in combination with cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy or hematopoietic stem cell transplantation. A total of 3 patients with MCD survived, with a median follow-up period of 69 months. The present study indicates that complete surgical resection is currently the standard treatment for UCD. Perioperative use of multidetector computed tomography and the laparoscopic approach have certain advantages in UCD. Molecular target therapy is effective in patients with stable MCD, and hematopoietic stem cell transplantation may be beneficial in certain patients with MCD and disease progression.

Abstract
Unicentric Castleman’s disease (UCD) is a rare disorder of unknown etiology characterized by localized lymphoid tissue proliferation and interfollicular hypervascularity. A 33-year-old Caucasian female presented with vague abdominal discomfort and pain with pressure. Ultrasound and computed tomography detected a large peripancreatic mass. Robotic-assisted resection of the mass along with en bloc dissection of the encased left adrenal gland was done. Frozen section examination confirmed UCD hyaline vascular variant in a retroperitoneal accessory spleen. Preoperative diagnosis of UCD is difficult due to its lack of specific symptoms and its cytologic similarity to reactive lymphadenopathy and other lymphoproliferative disorders. Surgical resection is standard treatment and provides the pathological specimen required for diagnostic confirmation. Here, robotic-assisted laparoscopy allowed visualization, mobilization, precise resection and extraction of the mass from a difficult to access retroperitoneal region.

Abstract
OBJECTIVES The aim of the present study was to comprehensively summarize the epidemiological, clinicopathological characteristics, treatments as well as prognosis of Castleman's disease (CD) identified in the oral maxillofacial and neck region. MATERIALS AND METHODS Patients with CD in the oral maxillofacial and neck were retrieved from disease registry at our institution from Jan. 1990 to Dec. 2015. Systematic reviews from both English and Chinese literature were performed to collect the detailed information about the oral maxillofacial and neck CD. The epidemiological, clinicopathological data and treatment outcomes were further statistically analyzed. RESULTS Four patients with the oral maxillofacial and neck CD were identified and histologically confirmed as hyaline-vascular type. They underwent surgical excision without recurrence during the follow-up. Systematic literature reviews identified 221 cases from 123 eligible articles which satisfied the inclusion criteria. In 225 patients, most patients were diagnosed as unicentric (207) or hyaline-vascular type (205) of CD and identified in the neck, and treated by surgical resection with good prognosis. In contrast, the minority of patients was multicentric or plasma-cell/mixed type and treated by chemotherapy with inferior outcomes. Kaplan-Meir analyses revealed that both clinical and pathological types were significantly associated with patients' overall survival. CONCLUSIONS Although rare, most cases of the oral maxillofacial neck CD are found in adults and classified as unicentric and hyaline-vascular type of CD. Complete surgical excision is preferred with favorable prognosis for unicentric disease, whereas chemotherapy is usually exploited for multicentric disease with inferior outcomes. CLINICAL RELEVANCE These data provide comprehensive information about the epidemiology, clinicopathological features, treatments, and outcomes of the oral maxillofacial and neck CD.

Abstract
Background POEMS syndrome is a rare multi-systemic disease characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. Arterial or venous thrombosis is a less-common complication of POEMS syndrome. Ischemic stroke has also been reported sporadically. However, the association between POEMS syndrome and ischemic stroke has not been entirely understood. Methods A case of ischemic stroke caused by cerebral vasculitis in a patient with POEMS syndrome was presented. Then a comprehensive review and analysis of the literature were performed. Results A total of 28 patients were identified. The common clinical manifestations of POEMS syndrome were rather non-specific in patients with ischemic stroke compared with those of patients without ischemic stroke. Twenty patients were found with multiple ischemic lesions (71.5%). In the 25 patients who had undergone the evaluation of cerebral arteries, nineteen patients (76.0%) were found with cerebral vasculopathy. Twelve patients (48.0%) had more than one cerebral artery involved. Ischemic events were documented in 8 patients even when they were undergoing all the therapy for ischemic stroke. Ten (55.6%) of the 18 patients who had survival data died within two years after stroke events. Conclusion Comprehensive analysis of literature revealed several trends in patients with ischemic stroke and POEMS syndrome including a low survival rate and a preponderance of cerebral vasculopathy and multiple cerebral arteries affected. Ischemic stroke may be a poor outcome predictor in patients with POEMS syndrome. Further researches focusing on a larger cohort may help in better characterizing and treating this rare complication of POEMS syndrome.

Abstract
A large volume of trials involve invasive, nontherapeutic research procedures, like organ biopsy or sham surgeries, that can pose risks comparable with the experimental treatment itself but that have no direct benefit for volunteers. Though such procedures can enhance the value of clinical investigations, recent studies suggest that many studies involving invasive, nontherapeutic research procedures are not well planned and reported; some studies suggest that their results are often not utilized in the planning of new investigations. This commentary offers recommendations for how investigators, sponsors, and ethics committees might improve evaluation and implementation of studies involving invasive nontherapeutic procedures. We conclude by urging more demanding scientific standards for the rationale, design, and reporting of burdensome, nontherapeutic research procedures-particularly where they involve risk of serious complications.

Abstract
Castleman disease (CD) describes a group of three rare and poorly understood lymphoproliferative disorders that have heterogeneous clinical symptoms and common lymph node histopathological features. Unicentric CD (UCD) involves a single region of enlarged nodes. Multicentric CD (MCD) involves multiple regions of enlarged lymph nodes, constitutional symptoms, and organ dysfunction due to a cytokine storm often including interleukin 6. MCD is further divided into Human Herpes Virus-8 (HHV-8)-associated MCD, which occurs in immunocompromised individuals, and HHV-8-negative/idiopathic MCD (iMCD). Recently, iMCD has been further sub-divided into patients with TAFRO syndrome, which involves thrombocytopenia (T), anasarca (A), fevers (F), reticulin myelofibrosis (R), organomegaly (O), and normal or only slightly elevated immunoglobulin levels, and those who do not have TAFRO syndrome. Non-TAFRO iMCD patients typically have thrombocytosis, less severe fluid accumulation, and hypergammaglobulinemia. iMCD patients with TAFRO syndrome may have a worse prognosis, but more research is needed.

Abstract
A 59-year-old man presented with multiple dark red erythemas with induration, anemia, and polyclonal hypergammaglobulinemia. A skin biopsy revealed the infiltration of lymphocytes and plasma cells and he was initially diagnosed with multicentric Castleman's disease (MCD). Glucocorticoid treatment was only partially effective. Four years later, the patient's bilateral lacrimal glands gradually became enlarged and a biopsy revealed dense lymphocyte and plasma cell infiltration with an IgG4+/IgG+ plasma cell ratio of 70%. The patient was diagnosed with IgG4-related disease (RD). Rituximab only had a slight effect. This case demonstrates that overlapping features of IgG4-RD and MCD may present in a single patient, which suggests a shared pathogenesis.
