[A rare case of an extra-pulmonary tuberculosis]

This is a case report on a 42-year old West. German woman suspected of suffering from an extrapulmonary manifestation of mucous membrane tuberculosis of the ethmoid sinuses. The condition did not improve after application of specific chemotherapy. Only after histological examination of several tissue samples was a direct connection with initial stage Wegeners granulomatosis established. Attention must be drawn to the fact that in isolated cases the differentiation between the histological diagnosis of tuberculosis versus Wegeners disease is complex and often faulty.
