More than 1 asbestos body (AB) per ml of bronchoalveolar lavage fluid (BALF) under light microscopy was defined as AB positive (ABP) and suggests an occupational asbestos exposure. We microscopically evaluated the AB number per one ml of BALF, which we defined as the AB concentration (ABC), using bronchoalveolar lavage (BAL) cytocentrifuge slides obtained from 35 patients having pulmonary nodular lesions (20 carcinoma and 15 nonneoplastic disease) and examined the correlation between ABC and clinicopathological data including findings on Helical computed tomography scan (HCTS) and occupational history of asbestos exposure (OHAE). BAL was performed by the standard technique without removing mucous with a gauze filter. AB was microscopically defined as a structure consisting of a core of transparent asbestos surrounded by an iron-protein coat. Twenty of 35 patients were ABP (ABP rate; 57%) and ABC ranged from 0 to 207.98/ml (mean ABC; 11.33/ml). Mean ABC was significantly higher in patients with OHAE (15.04/ml) compared to that in patients without OHAE (3.23/ml). Twenty-two of 35 patients (63%) lacked abnormality on HCTS and among these, 12 patients (55%) were ABP. In 20 pulmonary carcinoma patients, the ABP rate was 85% and ABC ranged from 0 to 31.1/ml (Mean ABC; 2.99/ml). The ABP rate of pulmonary carcinoma patients was 40% (8 patients) and among these, 5 patients (63%) did not show any abnormality on HCTS. In conclusion, our method was simple and useful and should be applied to patients with pulmonary nodular lesions and OHAE, even if there are no abnormalities on HCTS.
