[Pathogenesis of extrapulmonary tuberculosis (author's transl)].

Extrapulmonary tuberculosis generally develops from the lymphonodular part of the pulmonary primary complex by early or late haematogenous dissemination. Its manifestation depends especially on the time of latency of metastases. At present tuberculosis of the peripheral lymphnodes, the genitourinary system, the skin as well as the bones and joints are most frequently found in our area. They mainly develop from reactivation or late haematogenous dissemination in older patients.
