Rationale: Richter syndrome (RS) defines the transformation of chronic lymphocytic leukemia (CLL) into a more aggressive lymphoma. Although the term RS is most often reserved for transformation of CLL into diffuse large B-cell lymphoma (DLBCL), and less frequently Hodgkin lymphoma , the list of cases with more variable presentations in the literature is growing.

Patient Concerns: A 71-year-old Caucasian man initially consulted an otolaryngologist for a 1-year history of nasal congestion. Read More

Lymphomatoid granulomatosis (LYG) is a rare, extranodal B-cell lymphoproliferative disorder. The disease commonly presents with nonspecific symptoms and imaging features, making the diagnosis and therapeutic response assessment difficult. While histopathology is the mainstay of diagnosis, different imaging modalities such as computed tomography (CT), magnetic resonance imaging, or F18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) can help in identifying the different organs involved.

Lymphomatoid granulomatosis (LYG) is a rare Epstein-Barr virus (EBV)-driven B-cell lymphoproliferative disease (LPD). This disease is hypothesized to result from defective immune surveillance of EBV, with most patients showing evidence of immune dysfunction, despite no known primary immunodeficiency. Pathologically, LYG is graded by the number and density of EBV+ atypical B cells, and other characteristic findings include an angioinvasive/angiodestructive reactive T-cell infiltrate and various degrees of necrosis.

Lymphomatoid granulomatosis (LYG) is an extremely rare angio-centric and angio-destructive B-cell lymphoproliferative disease. Driven by Epstein-Barr virus (EBV), LYG predominantly involves the bilateral lungs. Commonly presenting as multiple nodules in the lung, pulmonary LYG can masquerade as various infectious diseases, vasculitis, lung cancer, or other metastatic neoplasm. Read More

Lymphomatoid granulomatosis (LYG) is an angiocentric, angiodestructive lymphoreticular proliferative disease that usually affects the lungs but it has been speculated to also effect the central nervous system (CNS). However, unique primary LYG of the CNS has rarely been reported in the literature. Herein, we describe a clinical case of a 37-year-old female patient with grade 1 primary CNS-LYG having a good prognosis owing to corticosteroid treatment. Read More

Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive lymphoproliferative disease which can involve multiple organs of the body and is most common in the lungs. Its pathological features are proliferation of large atypical B-cells related to Epstein-Barr virus, T-cell infiltration and tissue necrosis. This disease is rare, and LYG which uniquely involves the central nervous system (CNS) is extremely rare. Read More

Introduction: Traumatic Ulcerative Granuloma with Stromal Eosinophilia (TUGSE) is a rare oral ulcerated lesion of uncertain etiology, showing eosinophil-rich granulation tissue, with occasional large atypical CD30 positive mononuclear cells. It had been suggested that it may represent an oral counterpart of cutaneous lymphomatoid papulosis, with a potential to evolve into CD30 + T cell lymphoma OBJECTIVES: To compare TUGSE and non-specific oral ulcers (NSU) clinically, histopathologically and by clonality analysis for T-cell receptor re-arrangement, aiming to determine whether TGUSE with atypical cells is a lymphomatous premalignant condition, and whether therapeutic approach should be radical or conservative.

Interleukin-2-inducible T cell kinase (ITK) is critical for T cell signaling and cytotoxicity, and control of Epstein-Barr virus (EBV). We identified a patient with a novel homozygous missense mutation (D540N) in a highly conserved residue in the kinase domain of ITK who presented with EBV-positive lymphomatoid granulomatosis. She was treated with interferon and chemotherapy and her disease went into remission; however, she has persistent elevation of EBV DNA in the blood, low CD4 T cells, low NK cells, and nearly absent iNKT cells.

Although about 90% of the world's population is infected by EBV only a small subset of the related infections result in neoplastic transformation. EBV is a versatile oncogenic agent involved in a multitude of hematopoietic, epithelial, and mesenchymal neoplasms, but the precise role of EBV in the pathogenesis of many of the associated lymphoid/histiocytic proliferations remains hypothetical or not completely understood. Additional studies and use of evolving technologies such as high-throughput next-generation sequencing may help address this knowledge gap and may lead to enhanced diagnostic assessment and the development of potential therapeutic interventions.

Objective: To evaluate the accuracy of the recently proposed diagnostic criteria for chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS).

Methods: We enrolled 42 patients with hindbrain punctate and/or linear enhancements (<3 mm in diameter) and tested the CLIPPERS criteria.

Results: After a median follow-up of 50 months (IQR 25-82), 13 out of 42 patients were CLIPPERS-mimics: systemic and central nervous system lymphomas (n=7), primary central nervous system angiitis (n=4) and autoimmune gliopathies (n=2). Read More

Lymphomatoid granulomatosis (LYG) is an uncommon angiocentric and angiodestructive T-cell rich, Epstein-Barr virus (EBV) positive B-cell multisystem lymphoproliferative disorder, predominately affecting the lungs. Since both clinical presentation and radiographic imaging findings, including X-ray and computed tomographic (CT), are nonspecific, the ultimate diagnosis of LYG relies on lung tissue sample diagnosis with its WHO grading based on the degree of cytologic atypia, necrosis and density of EBV positive B-cells. In addition, its histopathologic grading is correlated with clinical manifestation with high grade LYG mimicking aggressive B-cell lymphoma. Read More

Lymphomatoid granulomatosis (LYG) is a rare B-cell lymphoproliferative disorder driven by Esptein-Barr virus (EBV) that most commonly affects the lungs, although extra pulmonary sites like the central nervous system, skin, liver and kidney can also be involved. It is microscopically characterized by an angiocentric and angiodestructive growth pattern, predominantly composed by small T-cells, although a smaller population of atypical large B-cells is considered the true neoplastic component. Oral cavity involvement of LYG has rarely been described and the diagnosis of this neoplasm is very difficult. Read More

The contribution of Epstein-Barr virus (EBV) to the development of specific types of benign lymphoproliferations and malignant lymphomas has been extensively studied since the discovery of the virus over the last 50 years. The importance and better understanding of the EBV-associated lymphoproliferative disorders (LPD) of B, T or natural killer (NK) cell type has resulted in the recognition of new entities like EBV+ mucocutaneous ulcer or the addition of chronic active EBV (CAEBV) infection in the revised 2016 World Health Organization (WHO) lymphoma classification. In this article, we review the definitions, morphology, pathogenesis, and evolving concepts of the various EBV-associated disorders including EBV+ diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS), EBV+ mucocutaneous ulcer, DLBCL associated with chronic inflammation, fibrin-associated DLBCL, lymphomatoid granulomatosis, the EBV+ T and NK-cell LPD of childhood, aggressive NK leukaemia, extranodal NK/T-cell lymphoma, nasal type, and the new provisional entity of primary EBV+ nodal T- or NK-cell lymphoma.
