Abstract:
Objectives: This study was carried out to ascertain the aetiology of exudative pleural effusions
when other diagnostic investigations such as pleural fluid and sputum examination for cytology and
acid fast bacilli fail to yield a definitive diagnosis and to differentiate between tuberculosis and
malignancy in cases suspicious of malignancy. Methods: Pleuroscopic biopsies were obtained in
219 cases by Chest Physicians in the endoscopy suite using flexi-rigid fiber-optic pleuroscopes.
Histological sections were stained with H&E and microscopic examination performed. Ziehl-Nielsen
stain for acid fast bacilli was performed in all suspected tuberculosis cases and immunohistochemistry
for Thyroid transcription factor 1 and other markers were carried out for all cases suspicious of
malignancy. Results: Adequate biopsy material for interpretation was obtained in 210 (95.9%) of
219 cases. Histopathology revealed 79 (37.6%) cases were tuberculosis, 64 (30.5%) were malignant
(primary from lung and other sites), 62 (29.5%) were non-specific inflammation and 5 (2.4%) were
empyema. A definitive diagnosis of tuberculosis, malignancy and empyema was obtained in 70.5%
of cases. Tuberculosis was encountered in a younger age-group than malignancy. Mean age for
tuberculosis patient was 49 years while for malignant patients was 63 years. The majority (79.6%)
of malignances encountered were metastatic lung adenocarcinoma.
