[A case of relapsing sarcoidosis with pleurisy 14 years after spontaneous remission].

An 83-year-old woman was referred to our hospital with dyspnea on exertion and right pleural effusion. At the age of 69, she had been given a clinical diagnosis of sarcoidosis due to uveitis, bilateral hilar lymphadenopathy, bilateral multiple nodular shadows on chest images, and serum angiotensin-converting enzyme (SACE) level elevation. Remission was spontaneous. The pleural effusion was exudative lymphocyte-rich. On thoracoscopy, the macroscopic appearance of the parietal pleura was telangiectasia without nodular lesions and the pleural biopsy specimens revealed non-caseating epitheloid cell granulomas whose cultures were negative for acid-fast bacilli and fungi. A tuberculin skin test and QFT-2G were negative, thus we diagnosed sarcoidsis pleurisy.
