Abstract

A fibroepithelial polyp of the bronchus is a rare, benign, and endobronchial tumor, histologically consisting of fibrovascular stroma covered by normal respiratory epithelium. We report a case of a fibroepithelial polyp arising from the left main bronchus. On CT, a characteristic lobulating contour of the endobronchial nodule was well visualized, which histopathologically represented a typical papillary growth pattern of the nodule. Such a lobulating contour of the nodule might help make a correct diagnosis of this rare disease among other various endobronchial neoplasms.

  Fig. 1 CT and histopathologic findings of endobroncbial fibroepithelical polyp in 47-year-old male. A. Axial chest CT scan (5-mm collimation) of lung window setting obtained at level of left main bronchus showing intraluminal polypoid nodule with lobulating contour resembling blackberry (arrow). B. Photograph of bronchoscopic polypectomy specimen revealing well-circumscribed nodule showing lobulating contour with glossy surface, measuring 1.2 × 1.0 cm in diameter. C. Scanning photograph of sagittal section of polyp showing marked papillary projections of nodule (H & E stain, × 1). D. Low-power photomicrograph shows that polyp consists of fibrovascular stroma lined by normal respiratory epithelium (H & E stain, × 40).
