Abstract
The primary tbc lesion is localized mostly in the lungs, but not in the apices, as it was thought before, but in the marginal parts of the middle and lower lung fields. From here the infection spreads to the regional glands, and these glandular foci instead of the primary foci in the lungs form the so-called primary complex, which we still clinically are not able to recognize. With further spread of the process there comes a period of generalization: spreading along the lymphatic tracts, the infection affects distant glands, enters the blood and gives gematogenous metastases in various organs.
