title: Endobronchial mass caused by tuberculosis.
abstract: We report a case that illustrates an unusual manifestation of tuberculosis with massive atelectasis secondary to an endobronchial polypoid lesion. The rarity of this manifestation, coupled with the nonspecific findings on biopsy, delays recognition and therapy. Tuberculosis should be considered in the differential diagnosis of endobronchial mass lesions in the right clinical setting.
