Introduction:

Hyaline-vascular type unicentric Castleman disease (HV-UCD) is a classic variant of Castleman disease, characterized by localized lymph node hyperplasia. Due to its rarity, there have been few systematic reports summarizing its clinicopathological features globally. Also, its pathogenesis remains unelucidated. The present study aims to provide a detailed clinicopathological and transcriptomic analysis of HV-UCD to enhance the understanding of its underlying mechanisms at a molecular level.

Methods:

We conducted a clinicopathological analysis of 51 HV-UCD cases and performed whole transcriptome analysis on frozen lymph node specimens from four cases. Differentially expressed genes (DEGs) and Gene Ontology (GO) analyses were performed to identify significant pathways and biological processes involved in HV-UCD, with reactive lymphoid hyperplasia as control.

Results:

The mean age of HV-UCD patients was 42.8 years, with no significant gender differences. The most common sites involved were the abdominal cavity (n = 18, 35.3%), mediastinum (n = 11, 21.6%), and retroperitoneum (n = 9, 17.6%), with an average size of the lesions being 4.8 cm. Histologically, 33.3% of cases exhibited “dysplastic follicular dendritic cells (dFDCs)” characterized by multinucleation or large nuclei within and outside follicles, positive for follicular dendritic cells (FDC) markers. DEGs analysis compared to reactive lymphoid hyperplasia revealed significant upregulation of genes related to FDCs and angiogenesis. Notably, the placental growth factor (PGF), a proangiogenic factor and a member of the VEGF family, demonstrated significant overexpression. GO analysis identified significant enrichment of genes involved in angiogenesis, cell adhesion, tissue architecture, and humoral immunity.

Discussion:

This large cohort of HV-UCD cohort provides potentially novel clinicopathological insights. Gene expression analysis demonstrated increased expression of FDC-related genes, suggesting a pivotal role of FDCs in HV-UCD pathogenesis. The differences in the gene profiles related to angiogenesis may contribute to the distinct mechanisms and histological features of HV-UCD and iMCD-TAFRO, where HV-UCD is associated with hyalinization of vascular walls and iMCD-TAFRO is characterized by angiogenesis with endothelial cell swelling.

Conclusion:

The present results suggest the crucial role of FDCs in HV-UCD pathogenesis from the molecular features. Currently, there are no objective diagnostic markers for HV-UCD. Identifying these markers may lead to a clearer understanding of the disease pathophysiology and improve diagnostic accuracy for HV-UCD. Further investigation is warranted to verify the findings.

Idiopathic multicentric Castleman disease (iMCD) is a type of Castleman disease unrelated to the Kaposi sarcoma-associated herpesvirus/human herpesvirus type 8 (KSHV/HHV8) infection. Presently, iMCD is classified into iMCD-IPL (idiopathic plasmacytic lymphadenopathy), iMCD-TAFRO (thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly), and iMCD-NOS (not otherwise specified). The most common treatment for iMCD is using IL-6 inhibitors; however, some patients resist IL-6 inhibitors, especially for iMCD-TAFRO/NOS. Nevertheless, since serum IL-6 levels are not significantly different between the iMCD-IPL and iMCD-TAFRO/NOS cases, cytokines other than IL-6 may be responsible for the differences in pathogenesis. Herein, we performed a transcriptome analysis of cytokine storm-related genes and examined the differences between iMCD-IPL and iMCD-TAFRO/NOS. The results demonstrated that counts per million of STAT2, IL1R1, IL1RAP, IL33, TAFAIP1, and VEGFA (P < 0.001); STAT3, JAK2, MAPK8, IL17RA, IL18, TAFAIP2, TAFAIP3, PDGFA, VEGFC, CXCL10, CCL4, and CXCL13 (P < 0.01); and STAT1, STAT6, JAK1, MAPK1, MAPK3, MAPK6, MAPK7, MAPK9, MAPK10, MAPK11, MAPK12, MAPK14, NFKB1, NFKBIA, NFKBIB, NFKBIZ, MTOR, IL10RB, IL12RB2, IL18BP, TAFAIP6, TNFAIP8L1, TNFAIP8L3, CSF2RBP1, PDGFB, PDGFC, and CXCL9 (P < 0.05) were significantly increased in iMCD-TAFRO/NOS. Particularly, upregulated IL33 expression was demonstrated for the first time in iMCD-TAFRO/NOS. Thus, inflammatory signaling, such as JAK-STAT and MAPK, may be enhanced in iMCD-TAFRO/NOS and may be a cytokine storm.

Castleman disease consists of several lymphoproliferative subtypes that share some histological features in the lymph nodes. On the other hand, numerous clinical findings and etiologies make the disease challenging to understand. The origin of the disease is the hyaline vascular-type unicentric Castleman disease (UCD), first reported by Benjamin Castleman et al. in 1954. Although UCD is characterized by localized lesions and lack of symptoms, multicentric Castleman disease (MCD) with multiple lesions and systemic symptoms was reported by Frizzera in 1983. MCD is further divided according to KSHV/HHV8 infection status. In KSHV/HHV8-related MCD, viral infection signals lead to excessive cytokine production, and cause clinical and pathologic abnormalities. Some cases of plasma cell-type KSHV/HHV8-negative MCD can be found in association with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-proteins, and skin changes), which is a paraneoplastic syndrome. The others are idiopathic MCD, which are currently considered a heterogeneous group of diseases with overlapping pathological and clinical features. In this article, we summarize the historical evolution of Castleman disease to help understand the disease concept. We also review the latest ideas and definitions of the subtypes within the MCD spectrum and summarize the histopathological findings.

Primary gastrointestinal (GI) T-cell neoplasms are extremely rare heterogeneous disease entities with distinct clinicopathologic features. Given the different prognoses of various disease subtypes, clinicians and pathologists must be aware of the key characteristics of these neoplasms, despite their rarity. The two most common aggressive primary GI T-cell lymphomas are enteropathy-associated T-cell lymphoma and monomorphic epitheliotropic intestinal T-cell lymphoma. In addition, extranodal natural killer (NK)/T-cell lymphoma of the nasal type and anaplastic large cell lymphoma may also occur in the GI tract or involve it secondarily. In the revised 4th World Health Organization classification, indolent T-cell lymphoproliferative disorder of the GI tract has been incorporated as a provisional entity. In this review, we summarize up-to-date clinicopathological features of these disease entities, including the molecular characteristics of primary GI T-cell lymphomas and indolent lymphoproliferative disorders. We focus on the latest treatment approaches, which have not been summarized in existing reviews. Further, we provide a comprehensive review of available literature to address the following questions: How can pathologists discriminate subtypes with different clinical prognoses? How can primary GI neoplasms be distinguished from secondary involvement? How can these neoplasms be distinguished from non-specific inflammatory changes at an early stage?

The first case of hyaline vascular type of unicentric Castleman disease (HV-UCD) was reported more than six decades ago. Since patients with HV-UCD are often asymptomatic and this condition is generally discovered incidentally on imaging tests, most of the previous reports were of mediastinal origin detected by chest radiography. In recent years, improved access to imaging modalities has provided new insights in the diagnosis of this condition. In this study, we reviewed the detailed clinical and pathological findings of 38 HV-UCD cases (20 males and 18 females, mean age: 42.8 years). The most common site involved was the abdominal cavity (34.2%), followed by mediastinum (23.7%) and retroperitoneum (15.8%). In the abdominal cavity, mesenteric origin was the most common. The mean size of masses was 4.8 cm. Pathologically, thick hyalinized collagen fibers surrounding large blood vessels and calcification were observed (81.6% and 23.7%, respectively). Multinucleated giant cells resembling Warthin–Finkeldey cell were also observed in occasional cases (23.7%). This is a unique paper that summarizes detailed clinical and pathological findings of a large series of a rare disease. The clinical information presented in this paper is more plausible than previous views and is useful for accurate diagnosis and understanding of the disease.

Plasma cell type idiopathic multicentric Castleman disease (PC-iMCD) occasionally manifests as parenchymal lung disease. This study aimed to elucidate the detailed clinicopathological features of lung lesions in PC-iMCD and compare the findings with those in immunoglobulin (Ig) G4-related disease (IgG4-RD), the most difficult differential diagnosis of PC-iMCD. We analyzed the clinicopathological findings and immunohistochemical expression patterns of interleukin-6 (IL-6) and Igs in lung specimens from 16 patients with PC-iMCD and 7 patients with IgG4-RD. Histologically, pulmonary PC-iMCD could not be differentiated from IgG4-RD based on lesion distribution patterns, the number of lymphoid follicles and obliterative vasculitis, or fibrosis types. The eosinophil count was higher in the IgG4-RD group than in the PC-iMCD group (p = 0.004). The IgG4/IgG-positive cell ratio was significantly higher in the IgG4-RD group (p < 0.001). The IgA-positive cell count and IL-6 expression intensity were higher in the PC-iMCD group than in the IgG4-RD group (p < 0.001). Based on these findings, we proposed a new diagnostic approach to differentiate lung lesions of PC-iMCD and IgG4-RD. Our approach can be utilized to stratify patients with suspected lung-dominant PC-iMCD to identify candidates for strong immunosuppressive treatment, including IL-6 blockade, at an early stage.

This study retrospectively evaluated the computed tomography (CT) findings of idiopathic multicentric Castleman disease (iMCD) at a single center and compared the CT findings of iMCD-TAFRO with those of iMCD-non-TAFRO. CT images obtained within 30 days before diagnostic confirmation were reviewed for 20 patients with iMCD (8 men and 12 women, mean age 52.8 ± 12.3 years, range 25-74 years). Twelve patients were diagnosed with iMCD-TAFRO, five with iMCD-idiopathic plasmacytic lymphadenopathy, and three with iMCD-not otherwise specified. CT images revealed anasarca and lymphadenopathy in all 20 patients. The iMCD-TAFRO group showed significantly higher frequencies of ascites (100% vs. 37.5%, P = 0.004), gallbladder wall edema (75.0% vs. 12.5%, P = 0.020), periportal collar (91.7% vs. 25.0%, P = 0.004), and anterior mediastinal lesions (non-mass-forming infiltrative lesions) (66.7% vs. 12.5%, P = 0.028). Para-aortic edema tended to be more frequent in patients with the iMCD-TAFRO group (83.3% vs. 37.5%, P = 0.062), while the absence of anterior mediastinal lesions tended to be more frequent in the iMCD-non-TAFRO group (16.7% vs. 62.5%, P = 0.062). These CT findings may have clinical implications for improving the accuracy and speed of iMCD diagnosis and differentiating iMCD-TAFRO from other subtypes.

A 72-year-old male patient presented fatigue, anemia, elevated total protein, IgG, IgG4, IL-6, and vascular endothelial growth factor (VEGF) levels. Initial diagnostics suspected multiple myeloma. A plane computed tomography (CT) scan showed pneumonia and the enlargement of generalized lymph nodes. A lymph node biopsy revealed a mix of immature and mature plasma cells, significant IgG4-positive cells, and IL-6-secreting plasma cells, mimicking plasmacytoma, IgG4-related disease, and Castleman disease, ultimately leading to a diagnosis of hyper IL-6 syndrome. Treatment with antibiotics improved the patient's condition without the need for additional therapies, including tocilizumab.

A 79-year-old Japanese woman presented with exertional dyspnea. She had cardiac tamponade and urgent pericardial drainage was performed. Pathological findings from the pericardial fluid revealed non-germinal center B-cell (non-GCB) pericardial large B-cell lymphoma (CD10-, BCL6+, and MUM1+). Although a diagnosis of fluid overload-associated large B-cell lymphoma was considered, GCB nodal diffuse large B-cell lymphoma (CD10+, BCL6+, and MUM1+) was discovered through needle biopsy of the enlarged left axillary lymph node. Despite the two lymphomas exhibiting different expression levels of CD10, polymerase chain reaction assessing IgH gene rearrangement suggested a clonal relationship between them. Additionally, MYD88 L265P mutation was confirmed using Sanger sequencing in both samples, suggesting the MCD type. Our case highlights a discrepancy between the Hans' criteria and the gene expression profile-based cell of origin.

Introduction:

Kikuchi-Fujimoto disease (KFD), is a rare inflammatory disease of unknown etiology, typically presenting with transient fever and cervical lymphadenopathy. It is recently classified as a tumor-like lesion in the World Health Organization Classification 5th Edition. There are few large-scale studies on patient demographics and clinical course. This study aims to report detailed clinicopathological features of KFD.

Methods:

We reviewed 112 cases of KFD diagnosed at Okayama University Department of Pathology and Oncology, Okayama, Japan between 2012 and 2022. Patients who were diagnosed with autoimmune diseases or bacterial/tuberculous lymphadenitis after the initial presentation as KFD were excluded.

Results:

The average age of the included cases was 29.4 years (range:6 to 77 years) with slight female predominance (n = 51/115, 44.3% for male; n = 61/115, 53.0% for female). For the included cases of 30 years or older, there were more females than males. The cervical lymph nodes were the most commonly affected sites (85%). For the 70 patients who had complete follow-up data available in the electric medical records, the recurrence rate was 23%, without a difference between males and females. Laboratory tests demonstrated significantly lower complement 4 (C4) levels (p = 0.038) and a higher rate of positive antinuclear antibodies (p = 0.007) in the relapsed cases than in the cases without documented recurrence. The mean number of days prior to confirm the diagnosis was 71.5 days. Among the representative lymph node histology classification, proliferative type was the most common (n = 75; 77%), followed by necrotizing (n = 22; 22%), and xanthomatous (n = 1; 1%). The patients with necrotizing type had significantly enlarged lymph nodes (p = 0.047) and longer duration of symptoms (p = 0.009) compared to the proliferating type.

Discussion:

The present study provides data from a large KFD cohort to provide comprehensive clinicopathological information to date. While KFD is known to predominantly affect female, there were considerably more males up to age 30 than females, Being young and adolescent male KFD patients was associated with atypical features. Future studies are warranted to confirm the findings noted in the results, to clarify clinicopathological differences in the male young adolescent KFD, and further characterize the classical female KFD cases, including histological features, treatment responses, and association with autoimmune or malignant hematology conditions.

Conclusion:

In this study, we analyzed a large number of KFD cases and clarified characteristics. The comprehensive clinicopathological features provided by the present results may be useful in elucidating the pathogenesis and predicting the clinical course of such clinically challenging cases, including association with autoimmune diseases and its long-term outcomes.

Atypical lymphoplasmacytic and immunoblastic proliferation (ALPIBP) was first reported in 1984 as characteristic histological findings in lymph nodes associated with autoimmune diseases, but it has not been clearly defined to date. To summarize the histological characteristics and clinical diagnoses associated with ALPIBP, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including “atypical lymphoplasmacytic and immunoblastic lymphadenopathy” from their inception to December 27, 2023. We also summarized the courses of three cases with a pathological diagnosis of ALPIBP. Nine articles with 52 cases were included. Among the total of 55 cases, including the three from our institution, the median age of the cases was 63.5 years with a female predominance (69.5%). Lymphadenopathy was generalized in 65.6% and regional in 34.4% of cases. RA (24.4%), SLE (24.4%), and autoimmune hemolytic anemia (20.0%), were common clinical diagnoses. A combination of cytotoxic chemotherapy was used in 15.6% of cases due to the suspicion of malignancy. Nodal T-follicular helper cell lymphoma, angioimmunoblastic type, methotrexate-associated lymphoproliferative disorders, and IgG4-related diseases were listed as important diseases that need to be pathologically differentiated from ALPIBP. This review summarizes the current understanding of the characteristics of ALPIBP. Given that underrecognition of ALPIBP could lead to overdiagnosis of hematological malignancy and unnecessary treatment, increased awareness of the condition in pathologists and clinicians is crucial.
