Abstract:
Nodular and reticular opacities were detected in both lower lung fields of a 75-year-old man in 2000. Bronchoscopy revealed pulmonary sarcoidosis. In 2002, nodular and reticular opacities were shown in the right upper lobe, and video-assisted thoracoscopic surgery was performed. The histological findings revealed usual interstitial pneumonia (UIP)-like lesions, whereas non-caseous granulomas were not detected. In the present case of pulmonary sarcoidosis, nodular and reticular opacities were predominantly distributed in both lower lung fields, and the histological findings obtained by video-assisted thoracoscopic surgery showed UIP-like lesions. These findings may enlighten the assist in understanding of the process of development of pulmonary sarcoidosis.
