 | Media file 1: Sarcoidosis, thoracic. Crops of numerous papules on the back of 33-year-old woman. Some papules have become confluent. Note that the skin in between the papules is of normal color. These lesions are usually associated with a good prognosis in sarcoidosis. Note also the scar sarcoid. Scars become infiltrated and purple, resembling keloids. These occur in active disease. |
 | Media file 2: Sarcoidosis, thoracic. Close-up view of Image above. |
 | Media file 3: Sarcoidosis, thoracic. Lupus pernio affects poorly perfused areas, such as the nose, ear lobes, and fingers. These areas become swollen and indurated, with deep purplish red. The lesions are often associated bone cysts due to sarcoid granulomas, and the nasal bones may be eroded. In this 38-year-old woman, the lesions affect the periorbital areas and the nose. The fingers were also affected (not shown). |

 | Media file 7: Sarcoidosis, thoracic. Stage I disease. Standard posteroanterior chest radiograph in a 28-year-old man shows extensive bilateral hilar and mediastinal lymph node enlargement not associated with a pulmonary abnormality. |
 | Media file 8: Sarcoidosis, thoracic. Stage II disease. Chest radiograph in a 36-year-old woman shows mediastinal lymph node enlargement and bilateral pulmonary opacities. |
 | Media file 9: Sarcoidosis, thoracic. Pulmonary window CT image in the same patient as in Image 8 shows small nodules mostly along the bronchovascular bundles, giving the bronchi and vessels a beaded appearance. This distribution along the bronchovascular bundles accounts for the fact that transbronchial biopsy is usually successful for obtaining tissue for diagnosis. |
 | Media file 10: Sarcoidosis, thoracic. Posteroanterior (PA) chest radiograph in a 38-year-old man shows stage III disease associated with a tumefactive type of lung parenchymal involvement: opacities in the right and left midlung zones that mimic neoplasm. |
 | Media file 11: Sarcoidosis, thoracic. CT axial images through the thorax in the same patient as in Image 10. Left, Mediastinal window setting shows bilateral hilar adenopathy. Right, Pulmonary window image shows round pulmonary opacities. |
 | Media file 12: Sarcoidosis, thoracic. High-resolution CT scan in a young patient shows uniformly small, bilateral nodules in a miliary pattern. The patient also had mediastinal and hilar adenopathy. This is stage II disease. |
 | Media file 13: Sarcoidosis, thoracic. High-resolution CT scan in a young woman with a several-year history of sarcoidosis shows lung destruction with air-spaces, focal consolidation, and a fungus ball in a cavity in the left lower lung. This is stage IV disease. |
 | Media file 14: Sarcoidosis, thoracic. Posteroanterior chest radiograph shows enlarged calcified hilar lymph nodes with calcifications. |
 | Media file 15: Sarcoidosis, thoracic. Axial CT scan through the mediastinum in the same patient as in Image 14 shows extensive calcifications in the mediastinal and hilar lymph nodes. |
 | Media file 16: Sarcoidosis, thoracic. Contrast-enhanced axial CT image at the level of the aorta shows enlarged pretracheal and prevascular lymph nodes. |
 | Media file 17: Sarcoidosis, thoracic. Posteroanterior chest radiograph shows extensive lung parenchymal involvement. At this stage, the patient had moderate-effort dyspnea. Radiograph of the right hand in the same patient shows extensive sarcoid osseous lesions in the phalanges and metacarpals. |
 | Media file 18: Sarcoidosis, thoracic. Gallium-67 scans in a patient who had a normal chest radiograph. Study shows increased uptake in the lung fields, higher than the background activity. The appearances are compatible with pneumonitis secondary to sarcoidosis. |
 | Media file 19: Sarcoidosis, thoracic. Gallium-67 scans in a patient with biopsy-proved lung sarcoidosis. Note intense activity in the lung fields suggestive of pneumonitis secondary to sarcoidosis. |
