White Blood Cells

Causes of Atypical Lymphocytes (Reactive Lymphocytes)

Atypical lymphocytes are activated immune cells, often seen in infections. Their unique look aids diagnosis, but distinguishing it from cancer is important.

Hypersensitivity Reactions: Causes and Mechanisms

Hypersensitivity is an exaggerated, undesirable immune response to an antigen, causing tissue damage. It encompasses four types: IgE-mediated (allergies), cytotoxic, immune complex, and delayed cell-mediated reactions.

Basophilia (High Basophils)

Basophilia is when basophil count are elevated. It often signals underlying issues like MPNs, allergies, or inflammation.

Macrophage

Macrophages are essential immune cells that engulf and digest foreign particles, playing a crucial role in inflammation and tissue repair. They are found throughout the body and are involved in various diseases, including infections and cancer.

Basophils

Basophils are white blood cells that play a crucial role in allergic reactions and inflammation. They release histamine and other mediators, contributing to symptoms like sneezing, runny nose, and hives. Elevated basophil counts can be associated with certain conditions, such as asthma and chronic myeloid leukemia.

Multiple Myeloma

Multiple Myeloma

Multiple myeloma (MM) is a blood cancer that affects plasma cells. Plasma cells produce antibodies that help fight infection. In MM, plasma cells become abnormal and grow uncontrollably. This can lead to bone pain, anemia, and other complications.

Chronic Myeloid Leukemia (CML)

Chronic Myeloid Leukemia (CML)

Chronic myeloid leukemia (CML) is a cancer of the blood cells that begins in the bone marrow. It is caused by a genetic abnormality that results in the production of too many white blood cells.

Chronic Lymphocytic Leukemia (CLL)

Chronic Lymphocytic Leukemia (CLL)

Chronic lymphocytic leukemia (CLL) is a type of cancer that affects white blood cells called B lymphocytes. In CLL, B lymphocytes become abnormal and grow uncontrollably. This can lead to fatigue, swollen lymph nodes, and easy bruising or bleeding. CLL is a slowly progressing cancer affecting mainly the elderly
