Synovial chondrosarcoma, whether primary or secondary to synovial chondromatosis, is a very rare entity. These two entities share a rather similar profile, not only epidemiologically and clinically, but also radiologically and anatomopathologically. Thus, the distinction between synovial chondromatosis and synovial chondrosarcoma is a real dilemma. However, this distinction is of great interest, given the very different evolutionary and therapeutic modalities. In this work, we will report a case of synovial chondrosarcoma in a 62 years old woman, whose diagnosis was confirmed by a histological test. We will then discuss the contribution of the different authors, as well as all the scientific trials, aiming at establishing concrete and objective criteria, allowing to evoke the aggressiveness of the chondrosarcoma, hidden behind the benignity of the synovial chondromatosis.
