[Pleural sarcoidosis - a report of three cases].

Three patients with pleural sarcoidosis are reported. Pleural effusion in two patients and a massive pleural thickening that mimicked a tumour were observed. Histological examination of pleural biopsies revealed sarcoidosis. None of the patients received treatment. No recurrence of the pleural effusion was observed after a year of follow-up and the massive pleural thickening remained stable.
