Inflammatory endobronchial polyposis with bronchiectasis in cystic fibrosis

An unusual case of endobronchial polyposis associated with extensive bronch iectasis in the context of cystic fibrosis (CF) has been described. A 15-yr-old female patient with CF underwent partial pneumonectomy for exte nsive bronchiectasis and frequent infective pulmonary exacerbations. Cylindrical bronchiectasis with associated purulent bronchitis and bronchio litis, together with inflammatory polyposis, was noted in the resected lung . To the best of the authors' knowledge, this is the first report of multiple endobronchial polyposis and may represent a rare complication of bronchiec tasis in a patient with cystic fibrosis. On-going infection and the cellula r composition of the polyps are discussed in relation to their possible aet iological relevance and relationship to upper respiratory tract polyps.
