Brief summary (registry, in English)
Clear cell chondrosarcoma of bone is considered a low-grade malignant tumor in the last WHO classification of soft tissue and bone tumors; however, it is reported that recurrences and metastasis can occur. Considering the uncertain prognosis of this rare tumor, with some cases that historically seems to pursue a bad prognosis, we decided to collect all the Italian cases of clear cell condrosarcoma, in order to better understand its natural history and prognosis.
