About some masked forms of chronic primary tuberculosis

Domestic authors pay considerable attention to the "masks" of tuberculosis, which is associated with the difficulties of their diagnosis [2, 3, 4, 5, 7]. Masked forms of tuberculosis are locally limited processes occurring with syndromes characteristic of non-tuberculosis diseases. Most often, these forms are observed in primary tuberculosis, especially in its chronic course. Chronic primary tuberculosis, first described by V. T. Shvaytsar, is a peculiar form of bronchoadenitis and is characterized by the presence of calcification sites and significant caseous changes in the affected lymph nodes, which serve as a source of prolonged intoxication and sensitization of the patient's body.
