Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

9.7K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Primary Lymphoid Organs

16.0K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Lymphoid Cells and Tissues

3.4K
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

5.2K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

1.1K
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Summary
This summary is machine-generated.

Extranodal abdominal lymphoma, often seen in advanced non-Hodgkin lymphoma (NHL), frequently affects the liver and gastrointestinal tract, especially in immunocompromised patients. Imaging findings are variable, making lymphoma a key consideration in unexplained abdominal tumors.

Area of Science:

  • Oncology
  • Radiology
  • Gastroenterology

Background:

  • Extranodal manifestations are common in non-Hodgkin lymphomas (NHL), occurring in up to 40% of cases.
  • The incidence of extranodal involvement in NHL has been increasing.
  • Abdominal involvement is a significant aspect of extranodal disease.

Purpose of the Study:

  • To provide a comprehensive overview of lymphoma involvement in abdominal organs.
  • To detail lymphoma involvement in the gastrointestinal tract and peritoneal cavity.
  • To discuss the clinical implications of extranodal abdominal lymphoma.

Main Methods:

  • A selective literature search was performed.
  • Analysis included dedicated original research articles and reviews.
  • Relevant clinical guidelines were discussed.

Main Results:

  • Extranodal abdominal lymphoma typically presents as secondary involvement in advanced disease stages.
  • The liver and gastrointestinal tract are the most frequently affected sites.
  • Immunocompromised patients exhibit a higher prevalence of extranodal abdominal lymphoma.

Conclusions:

  • Imaging findings associated with extranodal abdominal lymphoma are diverse.
  • Lymphoma should be considered a critical differential diagnosis for indeterminate abdominal tumorous diseases.
  • Early recognition and diagnosis are crucial for patient management.
