Undifferentiated chondrosarcoma of extraskeletal supraclavicular localization

We reported a rare extraskeletal localization of undifferentiated chondroscarcoma in a 71-year old patient. The neoplasm with a 20-year history in the left supraclavicular region exhibited a rapid growth in only a few months. Six months after a total tumor excision the patient has been in an excellent general health condition, with no signs of either a local relapse or distant metastases.
