Classification[]

Lymph node adenitis[]

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:^{[citation needed]}

• Neck
  • Cervical adenitis is an inflammation of a lymph node in the neck.
  • 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.
• 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[]

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.^{[citation needed]}
