A Case Report of Clear Cell Chondrosarcoma (CCC) Sparing the Epiphysis and Literature Review of CCC

Clear cell chondrosarcoma (CCC) is a rare subtype of chondrosarcoma with a relatively low malignant potential, mainly diagnosed by its characteristic location in the epiphysis of long bones. We report the case of a 33-year-old gentleman who presented with pain, difficulty in walking and restricted range of motion of the right hip joint, with a lesion located in the proximal femoral metaphysis and completely sparing the epiphysis. Needle biopsy was consistent with CCC, which was extremely unusual considering the location of the tumour. The patient was treated by “en bloc” resection of the tumour along with femoral head and reconstruction with hemiarthroplasty. The final histopathology report confirmed the diagnosis with clear surgical margins. The aim of this case report and literature review was to highlight the unusual location of this rare tumour, as such an isolated case of CCC completely sparing the epiphysis has never been reported.
