    Clinico-morphological and immuno-histological data on 15 cases of marked lymphocytic lung tissue infiltration are presented. The nature of B- and T-lymphocyte distribution, their proliferative activity as well as patterns of distribution of cells synthesizing light chains of immunoglobulins are described. In 12 cases, lymphocytic interstitial pneumonia was diagnosed; it featured distinct boundaries between zones of B- and T-lymphocytes of proliferating and resting cells. However, non-Hodgkin's lymphoma (MALT) detected in 3 cases lacked such a pattern. That might be interpreted as a marker of the particular pathology.

    Pulmonary Tuberculosis IV

    Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
    Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
