Inflammatory Bronchial Polyps Associated With Asthma

Abstract

We report a case of inflammatory bronchial polyps associated with asthma in a 10-year-old boy. He expelled about 50 polyps varying in size from 0.4 to 1.8 cm without difficulty. Microscopically, the polyps were lined by columnar epithelium supported by stroma consisting of a loose connective tissue with many capillary vessels and a chronic inflammatory infiltration composed mainly of lymphocytes, plasma cells, and eosinophils. The blood and urine laboratory data were normal except for blood eosinophilia of 3% to 10%, and a chest roentgenogram that showed a left perihilar small nodular lesion and a small irregular area in the right upper lobe. Test results of pulmonary function and blood gases were normal. The association of bronchial inflammatory polyps with asthma and the clinical manifestation in this patient is very uncommon.
