Adenitis

Adenitis is a general term for an inflammation of a gland.[1] Often it is used to refer to lymphadenitis which is the inflammation of a lymph node.

Classification[edit]

Lymph node adenitis[edit]

Lymph adenitis or lymph node adenitis is caused by infection in lymph nodes. The infected lymph nodes typically become enlarged, warm and tender. A swelling of lymph nodes due to growth of lymph cells is called lymphadenopathy. Types include:

  • Neck
  • Abdomen
    • Mesenteric adenitis is an inflammation of the mesenteric lymph nodes in the abdomen. It can be caused by the bacterium Yersinia enterocolitica.[2] If it occurs in the right lower quadrant, it can be mistaken for acute appendicitis, often preceded by a sore throat. Clinical manifestations may include fever, right lower quadrant abdominal pain, nausea, and vomiting. Most often occurs in children age 5-14.

Other[edit]

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.
