- Certain infectious and parasitic diseases (A00-B99)
- A18 Tuberculosis of other organsA18.2 Tuberculous peripheral lymphadenopathy
In simple words: Tuberculous lymphadenopathy is a type of tuberculosis that affects lymph nodes in areas like the armpits and groin.It's caused by the same bacteria that cause lung tuberculosis.Symptoms can include enlarged lymph nodes, fever, night sweats, and weight loss.Severe cases can lead to significant swelling in the limbs.
Tuberculous peripheral lymphadenopathy. Tuberculous adenitis. Excludes2: tuberculosis of bronchial and mediastinal lymph nodes (A15.4) tuberculosis of mesenteric and retroperitoneal lymph nodes (A18.39) tuberculous tracheobronchial adenopathy (A15.4)
Example 1: A patient presents with swollen lymph nodes in the neck, along with fever, night sweats, and weight loss. A biopsy confirms the presence of Mycobacterium tuberculosis., A patient with a history of pulmonary tuberculosis develops enlarged, painless lymph nodes in the groin.Testing confirms tuberculous lymphadenopathy., A patient with HIV presents with multiple enlarged lymph nodes.Biopsy of one of the nodes reveals Mycobacterium tuberculosis, indicating tuberculous lymphadenopathy.
Documentation should include evidence of enlarged peripheral lymph nodes, relevant signs and symptoms (fever, night sweats, weight loss), results of diagnostic tests (blood tests, tuberculin skin test, biopsy), and confirmation of Mycobacterium tuberculosis.
