Hypereosinophilic Syndrome (HES)

Hypereosinophilic Syndrome (HES) is a rare disorder causing persistently high eosinophil levels, leading to organ damage and inflammation.

Leukemoid Reaction

Leukemoid reaction is a benign, reactive process with elevated LAP & no Philadelphia chromosome, unlike malignant CML.

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.

Basophilia (High Basophils)

White Blood Cells

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

Hypersensitivity Reactions: Causes and Mechanisms

White Blood Cells

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.
