A rare benign tumor mimicking malignancy

The admission chest X-ray revealed consolidation and atelectasis at basal part of the right lung (Figure 1). Chest computed tomography (CT) demostrated pleural thickening, pleural effusion, and middle lobe lateral segment atelectasis of the right side suggesting bronchial obstruction (Figure 2). The patient underwent fiberoptic bronchoscopy which showed an endobronchial polypoid lesion without a peduncle originating from the orifice of the lateral segment of the middle lobe (Figure 3). Mucosa of the lesion was shiny, thin, reddish, and had a rich vascularisation, mimicing a malignant tumor. Bronchoscopic resection was not considered feasible because it was impossible to clearly identify the tumor's endobronchial origin. Bronchial mucosal biopsy was not performed because of risk of hemorrhage. Bronchial lavage was performed from the lateral segment of the middle lobe. A rare benign tumor mimicking malignancy
