[Thymic carcinoma associated with pulmonary sarcoidosis].

A 54-year-old man who worked as a farmer was admitted to the hospital in August 1989 because of bilateral hilar adenopathy that was detected during a mass screening. Laboratory examination showed a high serum lysozyme level and the PPD skin test was negative. Examination of a specimen obtained by transbronchial lung biopsy revealed non-caseous epithelioid cell granuloma.
