The granulation tissue, which are found in nonspecific inflammation, occasionally seemed like round mass. We experienced and report four cases in which the granulation tissue presented as endobronchial mass on the bronchoscopy. The masses obstructing lobar or segmental bronchial oriface were round, smooth surfaced and pinkish except whitish one case. The granulation tissue caused by acute or chronic inflammations, should be considered to differentiate endobronchial mass.
