title: Synovial chondrosarcoma: report of two cases and literature review.
abstract: Synovial chondrosarcoma is a rare soft tissue tumor that can arise from a previous synovial chondromatosis or as de novo tumor. The clinical and radiological findings of this malignancy are very similar to those of aggressive synovial chondromatosis. Confusion with other joint pathologies makes the diagnosis of synovial chondrosarcoma difficult in most of the cases. We present one recently diagnosed and treated case of synovial chondrosarcoma. The review of our hospital database revealed one more similar case. In both cases the malignancy arose from a pre-existing synovial chondromatosis. We also present a literature review emphasizing the clinical and histological findings of this rare entity.
