title: Comparison of the diagnostic values of biopsies of the pleura and cytologic evaluation of pleural fluids.
abstract: Results of a comparison of the diagnostic efficacy of percutaneous needle biopsy of the parietal pleura with that of cytologic examination of pleural fluid sediment obtained concurrently from 166 patients with benign or cancerous pleural disorders are reported. Of 44 patients with confirmatory evidence of cancer involving the pleural surfaces, 43 had positive cytologic findings, whereas pleural biopsies were diagnostic in only 16 cases. Of a total of 122 patients with benign pleural diseases, cytology provided the diagnosis in two cases of eosinophilic pleurisy, and pleural biopsy contributed the diagnosis in four of ten cases of tuberculosis. The data indicate that percutaneous needle biopsy of the parietal pleura is less efficacious in the diagnosis of malignant pleural disease than is cytologic evaluation of the fluid sediment, whereas in the diagnosis of tuberculous pleurisy, pleural biopsy proved superior.
