Lymphopenia is a low lymphocyte count, weakening immunity. It increases infection risk and flags underlying issues like cancer or severe illness.
White Blood Cells
Monocytosis (High Monocytes)
Monocytosis: Elevated monocytes signal underlying health issues. Learn causes (infections, cancers), symptoms, diagnosis, and management.
Lymphocytosis (High Lymphocytes)
Lymphocytosis: High lymphocyte count. It can be a harmless immune response or signal serious conditions like leukemia.
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.

Eosinophilic Esophagitis (EoE)
EoE: Chronic esophageal inflammation. Dysphagia, food impaction. Diagnosis: endoscopy, biopsies. Treatment: diet, meds, dilation.
AL Amyloidosis (Primary Amyloidosis)
AL amyloidosis occurs when misfolded light-chain proteins deposit in organs. Prompt treatment improves outcomes.
Sjögren’s Syndrome
Sjögren’s syndrome: An autoimmune disease causing dry eyes, mouth. Systemic effects is possible. Early diagnosis & management are key.
Waldenström Macroglobulinemia
Waldenström Macroglobulinemia (WM): Rare lymphoma, excess IgM. Causes fatigue, neuropathy, & hyperviscosity. Early diagnosis & tailored treatment are key.
Dendritic Cells
Dendritic cells (DCs) process antigens & present them to T cells, triggering immune responses.
Natural Killer Cells
Natural Killer (NK) cells are vital immune cells that provide rapid defense against infections and cancer. They recognize and eliminate stressed or infected cells without prior sensitization, playing a key role in immunosurveillance.
