Abstract
BACKGROUND Lymphomatoid granulomatosis (LyG) is a rare extralymphatic lymphoproliferative disease characterized by lymphocytic invasion into vascular walls and damage to blood vessels. The lungs are affected in 90% of LyG cases, followed by the skin, central nervous system (CNS), kidneys and liver. CASE PRESENTATION Here we report a case of a young woman with LyG, with CNS involvement as the initial clinical manifestation. Computer tomography (CT) scans showed multiple nodular, patchy and flocculent high-density shadows in both lungs without mediastinal lymph node enlargement. Magnetic resonance imaging (MRI) scans showed multiple abnormal signal intensities in the right cerebellar hemisphere, frontal, parietal and temporal lobes, and dorsal brainstem, which became patchy and annular after enhancement. The post-operative pathological analysis of lesion samples confirmed the diagnosis of grade II LyG. CONCLUSIONS LyG should be concerned in young adults showing multiple radiological brain and lung lesions. Resection and postoperative medication of steroid hormones and IFN-α may be effective in the treatment of LyG.

Abstract
Simple Summary The group of B-cell lymphomas primarily involving the lung encompasses different histological entities with distinct biological aspects, while sharing some clinical and radiological features related to their common anatomic site of occurrence. Recent molecular advances in the molecular genetics of these lesions have substantially improved of our understanding of the mechanisms of lymphomagenesis, adding novel information to histology in order to better characterize and manage these diseases. This review summarizes the available clinical, radiological, pathological, and molecular data on primary pulmonary B-cell lymphomas, discusses the mechanisms of lymphomagenesis, and highlights the role of a multi-disciplinary management in overcoming the diagnostic and therapeutic challenges in this setting. Abstract Primary pulmonary B-cell lymphomas (PP-BCLs) comprise a group of extranodal non-Hodgkin lymphomas of B-cell origin, which primarily affect the lung without evidence of extrapulmonary disease at the time of diagnosis and up to 3 months afterwards. Primary lymphoid proliferations of the lung are most often of B-cell lineage, and include three major entities with different clinical, morphological, and molecular features: primary pulmonary marginal zone lymphoma of mucosa-associated lymphoid tissue (PP-MZL, or MALT lymphoma), primary pulmonary diffuse large B cell lymphoma (PP-DLBCL), and lymphomatoid granulomatosis (LYG). Less common entities include primary effusion B-cell lymphoma (PEL) and intravascular large B cell lymphoma (IVLBCL). A proper workup requires a multidisciplinary approach, including radiologists, pneumologists, thoracic surgeons, pathologists, hemato-oncologists, and radiation oncologists, in order to achieve a correct diagnosis and risk assessment. Aim of this review is to analyze and outline the clinical and pathological features of the most frequent PP-BCLs, and to critically analyze the major issues in their diagnosis and management.

Pathobiology and treatment of lymphomatoid granulomatosis, a rare EBV-driven disorder. Blood 2020; 135:1344-1352.

Abstract
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. Clinically, LYG universally involves the lungs with other common extranodal sites, including skin, central nervous system, liver, and kidneys. Nodal and/or bone marrow involvement is extremely rare and, if present, suggests an alternative diagnosis. Treatment selection is based on histologic grade and underlying pathobiology with low-grade disease hypothesized to be immune-dependent and typically polyclonal and high-grade disease to be immune-independent and typically oligoclonal or monoclonal. Methods of augmenting the immune response to EBV in low-grade LYG include treatment with interferon-α2b, whereas high-grade disease requires immunochemotherapy. Given the underlying defective immune surveillance of EBV, patients with high-grade disease may have a recurrence in the form of low-grade disease after immunochemotherapy, and those with low-grade disease may progress to high-grade disease after immune modulation, which can be effectively managed with crossover treatment. In patients with primary refractory disease or in those with multiple relapses, hematopoietic stem cell transplantation may be considered, but its efficacy is not well established. This review discusses the pathogenesis of LYG and highlights distinct histopathologic and clinical features that distinguish this disorder from other EBV+ B-cell LPDs and lymphomas. Treatment options, including immune modulation and combination immunochemotherapy, are discussed.

Abstract
Lymphomatoid granulomatosis (LYG) is a rare lung disorder diagnosed by radiological imaging of multiple pulmonary nodules and occasionally induced by methotrexate (MTX) use. To date, the treatment of LYG has not been standardized. We herein report the case of a patient with grade 3 MTX-related LYG who presented a bulky lung mass. Importantly, the disease condition only improved after the discontinuation of MTX and remained stable for more than 1 year. Chest physicians should be aware that LYG can develop as a single lung mass and spontaneously regress, even without aggressive chemotherapy, following the cessation of MTX.

Abstract
The differential diagnosis of pyrexia, lung nodules and granulomas includes tuberculosis, vasculitis and rarely a malignancy. In countries where tuberculosis or histoplasmosis is endemic, these are the first consideration and often ruled out by microbiological investigations. Vasculitis like granulomatosis with polyangitis (Wegener's granulomatosis), Churg strauss syndrome and sarcoidosis, which are the second consideration, are ruled out by serological investigations. Confirmation of malignancy merits histopathology. This case highlights how a rare diagnosis of pulmonary lymphomatoid granulomatosis was reached after an open lung biopsy. The following case also describes the natural history of this rare disease as it showed transient spontaneous remission but ultimately required therapy.

Abstract
Lymphomatoid granulomatosis (LYG) is a rare tumor with unknown etiology. Specific etiological factors for LYG are also unknown, although previous data indicates that LYG is an Epstein-Barr virus-associated B-cell proliferation associated with an exuberant T-cell reaction. According to the 2008 WHO classification, LYG is characterized by B-cell proliferation of B-lymphoma cells. Generally, treatment options for LYG are similar to those for diffuse large B-cell lymphoma. Unfortunately, LYG is a chemotherapy-resistant disease in certain patients and has a poor prognosis. The current study presents the case of a 19-year-old male patient with pulmonary LYG. The patient exhibited progressive disease following one cycle of chemotherapy with cyclophosphamide, adriamycin, vincristine and prednisone, and nodular lesions in the brain were diagnosed. Radiotherapy was delivered to the whole brain, however, this treatment did not prevent progression of the disease and the patient succumbed three months after initial presentation. An overview of the literature with regard to the etiology, clinical features, diagnosis and treatment options for LYG is also presented in the current case study.

Abstract
Lymphomatoid granulomatosis (LG) is a very rare, Epstein-Barr virus-associated lymphoproliferative disorder of B cells. Prognosis is poor, particularly after relapse and no curative treatment exists. We report the results of high-dose therapy and autologous stem cell transplantation (ASCT) or reduced-intensity conditioning and allogeneic stem cell transplantation (alloSCT) in patients with multiply relapsed LG. A European Group for Blood and Marrow Transplantation survey identified 10 patients who had received 9 ASCT and 4 alloSCT. All patients had active disease at the time of transplantation. With a median follow-up of 5.1 (range, 1.4 to 6.3) years, 6 patients are alive and disease-free. Two ASCT patients died of septicemia early after transplantation, and 1 committed suicide after being in continuous complete remission 19 months after ASCT. Another patient allografted 4 years after ASCT remained disease-free but died of severe graft-versus-host disease 3 months after alloSCT. High-dose therapy followed by ASCT and alloSCT are effective therapeutic options and should be considered in all patients with refractory and multiply relapsed LG.

Abstract
Lymphomatoid granulomatosis, described in 1972 by Liebow, is a rare, Epstein-Barr virus (EBV)-associated lymphoproliferative disorder, involving the lung, and often the skin or the central nervous system. It could have a systemic course making its diagnosis difficult. Controversy still remains about precise taxonomy and lymphomatoid granulomatosis is classified as a lymphoma, whose severity extends from indolent forms to aggressive large B cell lymphomas. Histology is essential and shows characteristically an inflammatory angiocentric infiltrate, composed with polymorphous mononucleated cells containing a varying number of large atypical CD20-positive B-lymphocytes within a background of numerous small reactive CD3-positive T-lymphocytes, often associated with necrosis. In situ hybridization often shows EBV RNA within atypical B-cells. Atypical large B-lymphocytes proportion and to a lesser degree EBV-positive B-lymphocytes proportion allow to classify the disease (grade I to III) and have a prognostic value. An aggressive form of B lymphoma occurs in 7 to 47% of cases during lymphomatoid granulomatosis course. Moreover, grade III diseases share numerous characteristics of lymphoma and often require chemotherapy. Several conditions mimic lymphomatoid granulomatosis, and include various hematologic malignancies (large B-cells lymphomas, T/NK lymphomas, post-immunodepression lymphoproliferative disorders) or granulomatosis with polyangiitis. The objective of this article is to review the clinical, radiological, histological and therapeutic characteristics of this rare disorder.

The current histological criteria for the diagnosis of lymphomatoid granulomatosis (LYG) are reviewed and summarized. The majority of patients present with multiple bilateral nodules involving the lung. Key histologic features necessary for the diagnosis include a mixed mononuclear cell infiltrate that shows vascular infiltration, appreciable numbers of T-cells, and variable numbers of CD20-positive B cells that show positivity for EBER by in situ hybridization.

Abstract
Disseminated Mycobacterium avium complex (MAC) infection is a rare but severe disease mostly seen in patients with AIDS. It has been previously described in patients suffering from other kinds of immunodeficiency (e.g. primary immunodeficiency diseases in children or hairy cell leukaemia). We report two cases of disseminated MAC disease in young women with extended granulomatosis that revealed a new form of severe immunodeficiency syndrome. Both clinical observations initially appeared to be very similar to WHIM syndrome (Warts, Hypogammaglobulinemia, Infection, Myelokathexis), a rare immunodeficiency disease correlated with CXC chemokine receptor 4 (CXCR4) mutation leading to an impaired internalization of the receptor upon its ligand CXCL12. We investigated the CXCR4 status of the lymphocytes in both patients and found a severe defect in CXCL12-promoted internalization but no mutation of its gene. Moreover, myelokathexis was not noted in bone marrow biopsies and therefore a diagnosis of WHIM syndrome could not be assessed. This immunodeficiency syndrome associated with CXCR4 dysfunction was responsible for severe MAC infection in our patients, with a fatal outcome in one case. It may be possible that these patients would have benefited from early antimycobacterial infection or azythromycin prophylaxis.

Abstract
Interleukin 7 receptor alpha chain (IL-7Ralpha) has recently been confirmed as the first non-HLA gene definitively associated with multiple sclerosis (MS). The protective haplotype (haplotype 2) has reduced splicing of exon 6, reduced production of soluble IL-7Ralpha, and therefore reduced interference with receptor binding to its ligands, IL-7, and thymic stromal lymphopoietin (TSLP). From a meta-analysis on 3,376 MS patients, 4,143 controls, and 1,333 trio families, although the most significant association is still seen with haplotype 2 (P = 7 x 10(-10)), the highest odds ratio is seen for haplotype 4 homozygotes (OR = 1.35, P = 0.001). The IL-7Ralpha proximal promoter contains response elements to interferon beta (IFN-beta), the most commonly used immunomodulatory drug in MS. We demonstrate that IL-7Ralpha is up-regulated in response to IFN-beta in vitro for haplotypes 1 and 2, but not 4. This difference can be seen in peripheral blood mononuclear cells (PBMC) from heterozygotes (P < 0.002, n = 10) and homozygotes (trend only), and in CD4 + CD45RO + and CD4 + CD45RA + cells. In PBMCs, IL-7Ralpha cell surface protein (CD127) is lower in haplotype 4 carriers than non-carriers after incubation with IFN-beta (P < 0.003, n = 20). Response to IFN-beta includes viral protection and immune modulation, processes that could be pathogenically significant in MS. The haplotype-dependent variation in the regulation of IL-7Ralpha by IFN-beta may contribute to the genetic association of IL-7Ralpha with MS.

Abstract
We present the case of a 57-year-old patient who was admitted with fever and disorientation. The cerebrospinal fluid showed a mild pleocytosis and increased protein content. MR imaging revealed multiple lesions, particularly in the subcortical white matter, with spot like central contrast enhancement. The diagnosis of lymphomatoid granulomatosis was finally made through open lung biopsy. Despite treatment with rituximab and, in the later course of the disease, additionally with cyclophosphamide, the patient died 3 months after the diagnosis was made.
