Description

Bronchoscopy with curettage was carried out after bronchoscopy on 19 cases who were highly suspected of tuberculoma on chest X-ray. However, Mycobacterium tuberculosis was detected in only 2 cases by curette and 5 cases by bronchial lavage after currettage. In 12 other cases, tuberculoma was confirmed by surgical resection in 3 cases and a definitive diagnosis was not obtained in 9 cases. Compared with peripheral lung cancer, few positive results are obtained in tuberculoma. It was suggested that positive or negative biopsy results depend on which part of the coin lesion was scratched by curette. It was speculated that the center of the coin lesion and its surrounding, respectively, should be sampled for cases of tuberculoma and cancer.
