Abstract:
A relative or absolute increase of lymphocytes in peripheral blood is a frequent incidental finding. The differential diagnosis of such a finding includes a broad spectrum ranging from normal variations to neoplastic diseases. As for other laboratory parameters lymphocytosis must be interpreted within a given clinical situation. Further diagnostics aim to reliably differentiate between reactive and neoplastic conditions. If a lymphoma or leukemia is suspected this should lead to a rapid hemato-oncological investigation.

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...

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...
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...
