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...

Lymphoid interstitial pneumonia (LIP) is a rare disease characterized by benign reactive polyclonal proliferation of bronchus-associated lymphoid tissue after exposure to inhaled or circulating antigen(s), leading to a disease symptomatology similar to idiopathic interstitial pneumonia. Its association with diseases that are caused due to immune dysregulation (autoimmune diseases, congenital/acquired immunodeficiency, and allogeneic bone marrow transplant) and response to immunomodulatory/suppressive medications suggests an immunologic pathophysiology...

Infections occur more frequently in patients receiving biologics. However, cryptococcal infection is uncommon in patients receiving tocilizumab, an interleukin-6 inhibitor, in contrast to patients receiving tumor necrosis factor-α inhibitors. In this report, we describe a case of disseminated cryptococcosis in a 55-year-old man who was receiving tocilizumab every 2 weeks along with daily prednisolone and cyclosporine for Castleman's disease. He initially developed cellulitis on both upper limbs, and his condition worsened despite antibacterial therapy...

Kaposi's sarcoma-associated herpesvirus (KSHV) is associated with the human malignancy Kaposi's sarcoma and the lymphoproliferative disorders primary effusion lymphoma and multicentric Castleman's disease. KSHV establishes lytic infection of monocytes in vivo, which may represent an important cellular reservoir during KS disease progression. KS tumors consist of latently infected endothelial cells; however, lytic phase gene products are important for KS onset. Early KS lesion progression is driven by proinflammatory cytokines supplied by immune cell infiltrates including T cells and monocytes...

CD20-negative diffuse large B-cell lymphomas (DLBCLs) constitute a rare and heterogeneous group of aggressive lymphomas. Known well-documented variants include plasmablastic lymphomas, primary effusion lymphomas, anaplastic kinase-positive large B-cell lymphomas, and large B-cell lymphomas arising in human herpesvirus 8 (HHV8)-associated multicentric Castleman disease. They impose diagnostic challenges for pathologists and therapeutic confrontations for clinicians. CD20 loss in B-cell lymphomas is a well-known phenomenon after rituximab therapy...

The latency-associated nuclear antigen (LANA) of the Kaposi sarcoma herpesvirus (KSHV) performs a variety of functions to establish and maintain KSHV latency. During latency, LANA localizes to discrete punctate spots in the nucleus where it tethers viral episomes to cellular chromatin and interacts with nuclear components to regulate cellular and viral gene expression. Using highly sensitive tyramide signal amplification (TSA), we determined that LANA localizes to the cytoplasm in different cell types undergoing the lytic cycle of replication after de novo primary infection and after spontaneous, TPA-, or ORF50/RTA-induced activation...

Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma characterized by overexpression of cyclin D1 resulting from t(11;14)(q13;q32) translocation. Herein, we report 3 cases of MCL with features of plasma cell-type Castleman disease (CD). The 3 patients were all men, ranging from 51 to 74 years in age, and they all presented with systemic lymphadenopathy with anemia, hypoalbuminemia, elevated serum levels of C-reactive protein, and polyclonal hypergammaglobulinemia. Lymph node biopsy specimens of the 3 cases showed histological features of plasma cell-type CD, including atrophic germinal centers and interfollicular plasmacytosis, with no light chain restriction...

INTRODUCTION: Castleman Disease (CD) is a rare lymphopro-liferative disorder with heterogenous clinical and pathological features. It is a rare disease with mention in the rare disease data of the orphanet. It can present as unicentric or multicentric disease. Hyaline vascular variant and plasma cell variant are the two pathological subtypes. Hyaline vascular variant accounts for nearly 80% to 90% of unicentric cases. Hyaline vascular subtype variant has follicular and stroma rich subtype...

Background. Transient inflammatory flares are common in clinical care of human immunodeficiency virus (HIV)-infected patients. In-depth investigations are not performed routinely because patients often recover without therapeutic interventions, and therefore, the etiologies of these inflammatory flares frequently remain unknown. Case. We report a case of an HIV-infected patient with recurrent inflammatory flares during several years in whom diagnostic workup with a lymph node biopsy finally revealed multicentric Castleman disease (MCD)...

OBJECTIVES: Differentiating IgG4-related disease (IgG4-RD) from multicentric Castleman's disease (MCD) is challenging because both diseases present high serum IgG4. The objective of this study is to clarify the differences in characteristics and identify a clinically useful approach to differentiate these two diseases. METHODS: Forty-five consecutive patients with untreated active IgG4-RD and 33 patients with MCD were included in this study, who visited our institution from January 2000 to August 2016...

TAFRO syndrome was first described as a variant of multicentric Castleman's disease with thrombocytopenia, anasarca, fever, renal dysfunction, and organomegaly. We report the case of a 25-year-old Caucasian male with diagnosis of TAFRO syndrome and present a literature review. The objective of the study was to compare TAFRO syndrome between Japanese and non-Japanese patients. Cases were included by searching the term "TAFRO" in the Medline database using PubMed between 2010 and 2016. The Student t test and Mann-Whitney U test were used to compare continuous variables...

Cutaneous and systemic plasmacytosis (CSP) is a rare lymphoproliferative disorder that mainly affects middle-aged Asian individuals. Although Castleman disease is often complicated with various renal involvements, glomerulonephritis associated with CSP, which is considered as a variant of Castleman disease, is rare. This report presents the case of a 41-year-old Japanese man with nephrotic syndrome associated with CSP. Renal biopsy findings showed focal segmental glomerulosclerosis (FSGS) and diffusely mild segmental mesangial proliferation...

Castleman's disease is a rare event that gastroenterologists should be familiar with. We present a case of Castleman's disease presenting as acute pancreatitis. The diagnosis was established by excisional biopsy of a superficial lymph node and the patient had a favorable prognosis with chemotherapy. This case is reminiscent of acute pancreatitis with multiple lymphadenopathy and should raise suspicion for Castleman's disease.
