Adenitis is generally defined as an inflammation of a gland. It is often used specifically to refer to lymphadenitis, which is inflammation of a lymph node.
Understanding Adenitis
Adenitis involves the inflammation of glandular tissue. While the term can apply to any gland in the body, it most commonly refers to the inflammation of lymph nodes.
- General Definition: Inflammation of a gland.
- Common Usage: Often used to refer to lymphadenitis, or inflammation of a lymph node.
Lymphadenitis Explained
Lymphadenitis is a specific type of adenitis affecting the lymph nodes. Lymph nodes are small, bean-shaped structures that filter lymph fluid, a clear fluid containing white blood cells, throughout the body. When lymph nodes become inflamed, usually due to infection, the condition is known as lymphadenitis.
Causes of Lymphadenitis
Several factors can lead to lymphadenitis, including:
- Infections: Bacterial, viral, or fungal infections are common causes.
- Other Inflammatory Conditions: Certain inflammatory conditions, such as autoimmune diseases, can also cause lymph node inflammation.
Symptoms of Lymphadenitis
- Swollen and tender lymph nodes
- Redness and warmth around the affected nodes
- Pain
Diagnosis and Treatment
Diagnosis typically involves a physical examination and may include blood tests or a lymph node biopsy. Treatment depends on the underlying cause and may include antibiotics for bacterial infections, antiviral medications for viral infections, or other treatments for inflammatory conditions.
