Abstract:

Primary renal lymphoma is rare, and most are intermediate- and high-grade lymphomas of B-cell lineage, such as diffuse large B-cellor Burkitt lymphoma. We report a case of low-grade B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) arising from the kidney. Only a few cases of primary renal MALT lymphoma have been published.

Abstract:

Introduction. The development of rabbit farming requires the breeding of new breeds of rabbits with accelerated growth intensity and increased productivity. Together with the acceleration of growth and development of somatic systems, the rates of morphogenesis and formation of organs that provide immune protection, in particular, lymphoid formations of the intestine, also change [1, 2]. Lymphoid formations associated with the intestinal mucosa in mammals are represented by the diffuse form of lymphoid tissue, lymphoid nodules, as well as clusters of diffuse lymphoid tissue and lymphoid nodules

Abstract:

Primary pulmonary lymphoma is a rare neoplasm characterized by the proliferation of lymphoid tissue affecting the lungs. The most common subtype is marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). Rarely, a MALT lymphoma transforms into a diffuse large B-cell lymphoma (DLBCL). Treatment options include chemotherapy, radiotherapy, immunotherapy, and surgery. Here, we describe a patient with a primary pulmonary MALT lymphoma transforming into DLBCL. The purpose of this case report is to raise awareness of the relevant clinical and imaging features and to emphasize the need for

Primary dural lymphomas are very rare tumors—usually low-grade B-cell lymphomas of mucosa-associated lymphoid tissue type or marginal zone B-cell lymphomas.

It is characterized by slow evolution and atypical clinical presentation which delays diagnosis.

The current classification of lymphoid neoplasms is based on clinical information, morphology, immunophenotype, and molecular genetic characteristics. Despite technical and scientific progress, some aggressive B-cell lymphomas with features overlapping between two different types of lymphomas remain difficult to classify. The updated 2008 World Health Organization (WHO) classification of Tumours of the Hematopoietic and Lymphoid Tissues has addressed this problem by creation of two new provisional categories of B-cell lymphomas, unclassifiable; one with features intermediate between diffuse la

Abstract:

Abstract Lymphomas of the uterine cervix are uncommon neoplasms and typically appear as diffuse cervical enlargement. We describe a rare case of primary high-grade lymphoma of mucosa-associated lymphoid tissue of the uterine cervix in a 46-year-old white woman. The tumor, incidentally disclosed at gynecological examination, appeared as a single common polyp. Immunohistochemical investigation found the lesion to consist of a monomorphic CD20-positive infiltrate of large blasts and rare intermingling centrocyte-like lymphoid cells.

Abstract:

Gastric lymphoma is the second most common finding in gastric malignancies worldwide. Gastric lymphoma is a lymphoproliferative disorder that originates in the stomach and encompasses various histological findings. In cases of gastric lymphoma, the most frequently diagnosed types are diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue (MALT) lymphoma. There is a known association between Helicobacter pylori infection and genetic mutations with the occurrence of gastrointestinal lymphoma. Treatment options for gastric lymphoma include observation, antibiotic therapy, rad

Abstract:

According to the literature, spontaneous remission of aggressive lymphomas is extremely rare; gastric non-Hodgkin lymphomas, such as mucosa-associated lymphoid tissue lymphomas, often regress due to Helicobacter pylori treatment or no progression, even in a watch-and-wait strategy. Although spontaneous remission of diffuse large B cell lymphomas in the stomach was very rarely reported, the follow-up periods of the cases of spontaneous remission are within 2 years and most cases are likely to relapse after the first remission. Here, we report that a diffuse large B cell lymphoma in the stomach

Abstract An 81-year-old woman experienced compression symptoms due to diffuse enlargement of the thyroid gland. The cytopathological results of thyroid fine-needle suggested malignancy. Therefore, she underwent bilateral thyroidectomy. Postoperative pathology indicated mucosa-associated lymphoid tissue (MALT) lymphoma. Three months later, she found a progressively enlarged mass in her neck. The biopsy showed MALT lymphoma with highly aggressive B-cell lymphoma transformation. 18F-FDG PET/CT showed increased metabolism in multiple lymph nodes.

Abstract:

AbstractOcular surface diseases (OSDs) represent a widely investigated field of research given their growing incidence and the negative impact on quality of life. During OSDs, cytokines generated by damaged epithelia trigger and deregulate the lymphoid cells composing the eye-associated lymphoid tissues, inducing an immune-mediated chronic inflammation that amplifies and propagates the disease during time. The conjunctiva-associated lymphoid tissue (CALT), given its particular position that permits immune cells covering the cornea, might play a crucial role in the development of OSDs. Despite

Abstract:

Lymphomas are solid tumors that arise from lymphoid tissue and present themselves as Hodgkin's or non-Hodgkin's lymphoma. Particularly gastrointestinal lymphomas can be clinically confused with other gastrointestinal tumors as well as with diffuse and inflammatory bowel disease. Early diagnosis and treatment bear vital importance in the management of lymphomas due to their high proliferation rates. In this report, we are presenting a case which initially displayed clinical and radiological signs of Crohn's disease, but was eventually diagnosed as Burkitt's lymphoma by laparotomy, and also we a

The tumor necrosis factor (TNF) receptor-associated factor 1 (TRAF1) is a member of the recently defined TRAF family. It takes part in the signal transduction of the TNF receptor 2 (TNFR2), the lymphotoxin-β receptor (LT-βR), CD40, CD30, and LMP1; is induced by LMP1 in vitro; and protects lymphoid cells from apoptosis. To identify the cells in which TRAF1 is active in vivo, we studied TRAF1 transcripts in normal lymphoid tissue, in Epstein-Barr virus (EBV)-induced lymphoproliferations, and in malignant lymphomas with special reference to those that overexpress the cytokine receptor CD30 and CD

Abdominal CT and EUS revealed a homogeneously hypoechoic lesion arising from the second layer of the stomach, without distant metastasis. Laparoscopic wedge resection was performed.

Abstract:

Non-Hodgkin lymphomas (NHLs) encompass a diverse group of neoplasms arising from the clonal proliferation of B-cell progenitors, T-cell progenitors, mature B-cells, mature T-cells, and natural killer (NK) cells. These malignancies account for over 90% of lymphoid neoplasms. The link between the gut microbiome and neoplasms has been extensively studied in recent years. Growing evidence suggests that the gut microbiome may be involved not only in the development of the disease, but also in modulating the efficacy of implemented therapies.

We also considered this case in the context of previous reports.
