title: Abrasive bronchial brushing cytology. A preliminary study of 200 specimens for the diagnosis of neoplastic and nonneoplastic bronchopulmonary lesions.
abstract: Two hundred subjects with chronic respiratory symptoms with a suspicion of malignancy were selected for bronchial brushing cytology. Prior sputum examination had shown malignant squamous cells in two cases only. The cytologic appearances of the brushing smears were divided into five categories: 41 (20.5%) smears with positively malignant cells; 20 (10%) smears predominantly showing chronic inflammatory features; 31 (15.5%) smears with mainly acute inflammatory changes; 60 (30%) smears with normal cytologic features; and 48 (24%) smears unsatisfactory for cytologic interpretation. Thirteen patients with a positive cytology had a positive tissue biopsy for malignancy. Among the group with chronic inflammatory changes, acid-fast bacilli were identified in nine cases, and one smear showed frank tuberculous granuloma. In the unsatisfactory group, two cases showed malignant cells in the postbrushing sputum. There was one false-negative report for malignancy in the entire study. This study confirms the sensitivity and accuracy of bronchial brushing cytology in the diagnosis of various bronchopulmonary lesions, especially malignancy and pulmonary tuberculosis, in India.
