Summary
This study details a patient with Common Variable Immunodeficiency (CVI) and large granular (LG) lymphocytosis who developed gastric diffuse large B-cell lymphoma. It
Area of Science:
- Immunology
- Oncology
- Hematology
Background:
- Common Variable Immunodeficiency (CVI) is a primary immunodeficiency characterized by low immunoglobulin levels.
- Large granular (LG) lymphocytosis is a condition involving an increase in a specific type of lymphocyte.
- Systemic lymphadenopathy refers to widespread swelling of lymph nodes.
Observation:
- A patient with CVI and LG lymphocytosis presented with non-malignant systemic lymphadenopathy.
- The patient subsequently developed diffuse large B-cell lymphoma (DLBCL) localized to the stomach.
Findings:
- This case represents the first documented instance of gastric high-grade lymphoma in a patient with LG lymphocytosis associated with CVI.
- The co-occurrence highlights a potential, previously unreported association between these conditions.
Implications:
- This finding may necessitate a re-evaluation of diagnostic and management strategies for CVI patients with LG lymphocytosis.
- Further research is warranted to explore the potential link between CVI, LG lymphocytosis, and the development of gastric lymphoma.
- Understanding this association could lead to earlier detection and improved outcomes for affected individuals.

01:16Primary Lymphoid Organs
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...

01:15Secondary Lymphoid Organs
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...

01:18Lymphoid Cells and Tissues
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...

01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
