ABSTRACT

Nowadays, bronchial tuberculosis is an uncommon, although probably underestimated, form of tuberculosis. The records of 23 patients hospitalized between 1978 and 1989 were reviewed retrospectively. Mean age was 57 years (range 22 to 84 years). Only one female patient of african origin was a recent immigrant. The disease was pseudo-tumoral in 2 cases and included lymph node fistulae in 4 cases. M. tuberculosis was found at microscopic examination in only 10 patients. The course of the disease was slow and sometimes erratic, even under a well-conducted medical treatment. In one of the female patients, a lymph node fistula appeared after 6 months of chemotherapy, and it is clear that medical treatment must be pursued well beyond the conventional time limits. Several mechanisms are responsible for bronchial tuberculosis either invasion of the neighbouring bronchi by pulmonary tuberculosis; or lymph node fistula now more frequently due to reactivation of old lesions than to a recent primary infection; or again primary bronchial lesions mimicking bronchial carcinoma.
