Abstract:
Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of extranodal large B-cell lymphoma characterized by a selective proliferation of lymphoma cells within the lumina of vessels. We report a case of an 86-year-old man who presented with fever, shortness of breath and altered mental status. The diagnosis of IVLBCL was confirmed on a bone trephine biopsy that revealed positivity of CD20 and PAX5 immunohistochemical staining of lymphoma cells confined within the lumina of vessels. The patient had a rapidly deteriorating clinical course with a fatal outcome even before the specific treatment for the underlying disease was commenced.

Lymphoid Cells and Tissues
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...
Disorders of Leukocytes
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...
Secondary Lymphoid Organs
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...
