A Case of Delayed Response of Tumorous type of Endobronchial Tuberculosis to Antituberculosis Treatment / 결핵및호흡기질환

Pulmonary tuberculomas show variable responses to treatment, with some even increasing in size after treatment. To date, however, no data have been reported on the response of tumorous type of endobronchial tuberculosis (EBTB-T) to treatment observed both bronchoscopically and histologically. We report a case of bacteriologically- and biopsy-proven EBTB-T that showed delayed response to anti-tuberculosis treatment. Even after EBTB-T was treated with antituberculosis drugs for 15 months, the bronchoscopic findings and the histologic findings of chronic granulomatous inflammation with caseation necrosis still remained. However, in fourteen months after the completion of treatment, the lesioneventually disappeared without further treatment.
