RESUMO
A 38 years old patient presented with a progressive reduction of his general condition and weight loss. Chest imaging revealed consolidations and cavities suggesting a mycobacterial infection. For further diagnosis, a bronchoscopy was performed. In fact, a nontuberculous mycobacterial infection was found. As an incidental finding, we saw a white polypoid tumor in the middle lobe bronchus. The histology of this tumor revealed a granular cell tumor (GCT). The GCT is a rare tumor entity which occurs at different anatomical locations. In the lungs, the GCT may become symptomatic as it can cause bronchial obstruction. In chest imaging, it can manifest as infiltration, atelectasis or nodule. Likewise, GCT can be found as an incidental finding in bronchoscopy. First choice treatment is surgical resection of the tumor.
