title: Pleural exudate in a tropical hospital.
abstract: In one hundred consecutive patients with non-purulent pleural exudates without apparent cause, the final diagnosis was tuberculosis in 58, malignancy in 20, pyogenic infection in four, cardiomyopathy in two, pulmonary infarction in one. The aetiology remained unknown in 15. The technique of "semi-open" pleural biopsy was performed under local anaesthesia. It accurately detected 70% of cancer and 69% of tuberculosis cases with a 9% complication rate and no mortality. Tuberculosis was seen at all ages but mainly between 20 and 39 yrs, where it represented 75% of cases. In this age group, malignancy was relatively rare: 10% of cases. In our environment of limited facilities, early chemotherapy trial for tuberculosis is justified for unknown pleural exudates in patients below the age of 40 yrs.
