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 (LG) is an EBV-associated angiodestructive lymphoproliferative disease with multiorgan involvement that predominantly affects the lungs. We present a case of a 72-year-old man with a history of chronic lymphocytic leukemia who presented with upper respiratory symptoms and multiple erythematous skin papules. Chest CT showed ill-defined, irregular solid pulmonary nodules with peripheral ground-glass opacities in a peribronchovascular distribution. Read More

Lymphoproliferative disorders can occur in patients with autoimmune disorders who undergo long-term methotrexate therapy (MTX-LPD). Although the manifestations of MTX-LPD are diverse, little attention is paid to endobronchial involvement. We herein describe two patients with MTX-LPD who presented with parenchymal pulmonary tumors and endobronchial involvement of LPD; one had lymphomatoid gramulomatosis and the other LPD. Read More

Background: Trigeminal neuralgia (TN) represents one of the most disabling pain syndromes. Several diseases have been described as etiological triggers of TN, vascular compression of the trigeminal nerve being the most frequent cause. Here, we describe for the first time a rare case of TN caused by an infiltration of an isolated Epstein-Barr virus (EBV) B-cell lymphomatoid granulomatosis (LYG) mass into the Meckel's cave and cavernous sinus.

We present serial F-FDG PET/CT findings in a case of grade 3 pulmonary lymphomatoid granulomatosis positive for the Epstein-Barr virus. The patient experienced a transient complete response to R-CHOP chemotherapy and subsequent multisystem recurrence, predominately involving the subcutaneous region of the torso on F-FDG PET/CT. Biopsy of the most hypermetabolic subcutaneous lesion demonstrated grade 1 cutaneous lymphomatoid granulomatosis negative for the Epstein-Barr virus. Read More

Cartilage-hair hypoplasia (CHH) is an autosomal recessive chondrodysplasia characterized by short-stature, sparse hair and impaired cellular immunity. We describe a young girl who was diagnosed with CHH based on the findings of recurrent infections, short stature with metaphyseal chondrodysplasia, and a confirmed bi-allelic RMRP gene mutation. At 13 years, the patient developed an Epstein-Barr virus (EBV)-driven lymphoproliferative disorder involving the lung, which responded partially to chemotherapy. Read More

Background: Angiocentric lymph proliferative disorder (ALPD) is a granulomatous lymphoproliferative condition associated with various primary and secondary immunodeficiency states. ALPD is so rare that its prevalence has not been established.

Lymphomatoid granulomatosis (LYG) is a rare lymphoproliferative disorder characterized by infiltration of Epstein-Barr virus (EBV)-positive large atypical B-cells in an angiocentric fashion in a mixed inflammatory background. The histologic spectrum of LYG ranges from reactive proliferation to diffuse large B-cell lymphoma according to the number of EBV+ B-cells. It is known that virtually all patients have pulmonary involvement, whereas primary LYG of the other organs has been rarely reported. 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.

Hodgkin lymphoma and lymphomatoid granulomatosis (LYG) are entities that contain a small number of large, variably Epstein-Barr virus (EBV)-positive neoplastic cells scattered within background non-neoplastic mixed inflammatory infiltrate. The 2 entities can typically be distinguished histologically by the angiocentric and angiodestructive pattern of lymphomatoid granulomatosis (LYG); also, they differ in overall prognosis. Herein, we report a case of Hodgkin lymphoma in a 64-year-old Caucasian woman, diagnosed at autopsy with unusual histologic features and aggressive clinical course that mimicked LYG. Read More

We present a 60-year-old woman with worsening fatigue, night sweats, unintentional weight loss, and dyspnea of 2 weeks' duration.

There were 10 men and 7 women with a median age of 59 years (range, 36 to 83 y). The primary hematologic neoplasms included: 5 chronic lymphocytic leukemia/small lymphocytic lymphoma, 3 plasma cell myeloma, 2 acute monoblastic leukemia, and 1 case each of mixed-phenotype acute leukemia, chronic myeloid leukemia, splenic marginal zone lymphoma, follicular lymphoma, mantle cell lymphoma, T-cell prolymphocytic leukemia, and peripheral T-cell lymphoma.

While the World Health Organization included Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) as a provisional entity of a lymphoma occurring in older individuals without any known immunodeficiency in 2008, it has since been recognized that this entity may occur in younger individuals. As a result, the 2016 revision has substituted the modifier "elderly" with "not otherwise specified" (NOS). The NOS highlights that there are more specific entities with neoplastic EBV-positive large B cells such as lymphomatoid granulomatosis. Read More

This review aims to describe some of the most frequent lymphoproliferative disorders arising from the lung: pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma, lymphomatoid granulomatosis (LG), multicentric Castleman disease (MCD), primary effusion lymphoma (PEL), and nodular lymphoid hyperplasia (NLH). Primary pulmonary lymphoma is defined as a clonal lymphoproliferative disorder affecting one or both lungs, without extrapulmonary involvement 3 months after diagnosis, and includes pulmonary MALT lymphoma and LG. MALT lymphoma is the most common pulmonary lymphoma. Read More

Epstein-Barr virus (EBV)-associated lymphoproliferations involving the skin are a rare but important group of diseases with a broad spectrum of behavior, ranging from self-limiting spontaneously resolving disorders to highly aggressive malignancies. They may be of B, T, or natural killer (NK) cell type and include EBV-positive mucocutaneous ulcer, lymphomatoid granulomatosis, EBV-positive diffuse large B-cell lymphoma, hydroa vacciniforme-like lymphoproliferative disorder, and extranodal NK/T-cell lymphoma of nasal type.
