To determine and compare the efficacy of pleural fluid cytology and closed needle biopsy of the pleura in establishing the diagnosis of malignant pleural effusions in Yaounde, we reviewed the medical records of all consecutive patients with a pleural effusion admitted in unit B of the Chest Clinic of the Jamot Hospital between January 1990 and December 1994. Fifty four cases of malignant pleural effusion were diagnosed over this period. Closed needle biopsy of the pleura alone permitted a diagnosis of malignancy involving the pleura in 32 instances while cytological studies of pleural fluid provided a diagnosis in thirty six cases. A combination of both techniques was diagnostic in 48 (88.9%) patients. We recommend that both pleural fluid cytology and closed needle biopsy of the pleura be used concomitantly in the evaluation of pleural effusion for which malignancy is suspected.
