Adenitis is a general term for an inflammation of a gland or lymph node.
[edit] Classification
Cervical adenitis is an inflammation of a lymph node in the neck.
Lymph adenitis is caused by bacterial infection in lymph nodes. The infected lymph nodes become enlarged, warm and tender. A swelling of lymph nodes due to growth of lymph cells is called lymphadenopathy.
Mesenteric adenitis is an inflammation of the mesenteric lymph nodes in the abdomen[1]. If it occurs in the right lower quadrant, it can be mistaken for acute appendicitis, often preceded by a sore throat.
Sebaceous adenitis is an inflammation of the sebaceous glands in the skin. These glands normally produce sebum (skin oil, a lipid-rich secretion) which prevents drying of the skin.
Tuberculous adenitis (scrofula) is a tuberculous infection of the skin of the neck caused by Mycobacterium tuberculosis. Non-tuberculous adenitis can also be caused by Mycobacterium scrofulaceum or Mycobacterium avium.
