Tuberculous lymphadenitis
Tuberculous lymphadenitis
Tuberculous lymphadenitis (pronunciation: too-ber-kyoo-lus lim-fad-uh-nahy-tis), also known as scrofula or King's evil, is a form of tuberculosis that affects the lymph nodes. It is the most common form of extrapulmonary tuberculosis.
Etymology
The term "tuberculous lymphadenitis" is derived from the Latin word "tuberculum" which means a small swelling or lump, and the Greek words "lymphaden" meaning lymph node, and "itis" indicating inflammation. The term "scrofula" comes from the Latin word "scrofulae" meaning brood sow, due to the resemblance of the disease's swollen lymph nodes to the sow's teats.
Symptoms
The primary symptom of tuberculous lymphadenitis is the presence of painless swelling in the lymph nodes, particularly those in the neck. Other symptoms may include fever, weight loss, night sweats, and fatigue.
Diagnosis
Diagnosis of tuberculous lymphadenitis typically involves a combination of physical examination, medical history, and laboratory tests. These may include a tuberculin skin test, blood tests, imaging studies such as ultrasound or CT scan, and biopsy of the affected lymph node.
Treatment
Treatment for tuberculous lymphadenitis usually involves a course of antituberculous therapy (ATT) for a period of six months. This typically includes a combination of drugs such as isoniazid, rifampicin, pyrazinamide, and ethambutol.
