OBJECTIVE: To investigate the radio-pathological features of @entity10070 . METHOD: Forty six consecutive @entity1 from January 2000 to August 2005 in Peking Union Medical College Hospital with pathologic features of epithelioid cell @entity738 were enrolled in the study. RESULTS: All the cases were confirmed by pathological findings consistent with sarciodosis. Bronchoalveolar lavage (BAL) fluid analysis showed that, the differential count of lymphocytes was 0.47 +/- 0.18, and the @entity1050 (4)/ @entity1050 (8) ratio was 6.63 +/- 4.51. Serum angiotensin converting enzyme level was (47 +/- 16) U/L. Chest computed tomography scan showed @entity3018 (33%, 12/46), well circumscribed pulmonary nodules (35%, 16/46) distributed randomly or along the bronchovascular bundle, patchy areas of alveolar consolidation (28%, 13/46), and bilateral ground glass infiltrations (11%, 5/46). Open lung biopsy, video-assistant thoracoscopic biopsy or mediastinoscopic biopsy were performed in 13 @entity1 , and percutaneous lung biopsy or transbronchial lung biopsy in 33 @entity1 . The characteristic pathologic finding was noncaseating epithelioid cell @entity738 , which were embedded in the substance of hyalinization. The @entity738 were distributed around blood vessels, lymphatics, or in the bronchial submucosa. @entity1333 was noted in some cases. CONCLUSION: The diagnosis of @entity370 can be proposed by clinico-radiologic and BAL fluid findings. However, histologic evidence of noncaseating epithelioid cell @entity738 and the therapeutic efficacy of glucocorticoids are essential to the final diagnosis.
