[Tuberculosis of jaw bones].

The authors report three cases of isolated tuberculous foci of jaw bones and stress the increase in the prevalence of tuberculosis in last years. The process had a protracted course and was associated with isolated or multiple pus-discharging fistulae. In all cases the final diagnosis was based on the histological examination of scrapings from the pathological lesions. In one case establishing of correct diagnosis was very difficult since the initial laboratory investigations and microscopic examination of cells from the pus and sputum failed to demonstrate specific changes. Only later histological examination during repeated exacerbations demonstrated tuberculosis. The treatment with tuberculostatic agents made possible achieving of improvement.
