Chronic Pulmonary Infection After Foreign Body Aspiration

Abstract

The removed lung measured 10X 10 x 6 cm. There was a large (4.5 ern) cystic lesion in the center, containing trabeculated structure and yellowish tan necrotic material (Fig. 3). A small amount of fresh hemorrhage was also noted. Granuloma and sulfur granules were also seen. Bronchiectatic cavity wall showed fibrosis. Microscopic examination showed numerous Gram-positive filamentous bacilli and some neut-rophils in the cavity content. The bacilli showed frequent colonized masses (sulfur granuies) (Fig.4) The cavity wall consisted of dilated bronchial structures with complete pithelial denudation, chronic inflammatory cell infiltration and fibrosis. The culture was not carried out with resected specimen.
