What Is Primary Complex And How It Is Diagnosed ?

Primary complex is an infection due to the tuberculosis bacteria. They can lodge in any part of the body. The tissues respond by accumulating white blood cells at the site of primary infection which is now called the primary focus. The tubercle bacilli from the primary focus are transported along the lymphatics to the regional draining lymph nodes, causing an inflammatory response as a result of which the lymph nodes enlarge. After a while the lymph nodes liquefy in the centre leading to the production of a thick white cheesy material.

These days the primary focus is usually diagnosed before this occurs. Any suspiciously enlarged, painless lymph nodes, especially if they are matted together are suspicious of a primary focus. These are subjected to FNAC (fine needle aspiration biopsy), the material obtained is sent for histopathological examination and the diagnosis confirmed. You will need anti-tubercular medication for at least a year. When the full treatment course is completed, you should be completely cured.  However, it is possible that at a larger stage, the primary complex may get reactivated if your general level of health or immunity were to decline for some reason.
