Two cases were presented with initial symptoms of inflammatory low back pain and alternate buttock pain. They developed a progressive dyspnea with bilateral mediastinal and hiliar lymphadenopathy and pulmonary interstitial disease as visualized with chest CT scan. Sarcoidosis diagnosis was confirmed by biopsy in both cases--in one case by skin biopsy and in the other by open lung biopsy. These clinical forms of spondyloarthropathy and sarcoidosis were unusual and were compared with similar cases present in the literature.
