Clear cell chondrosarcoma of proximal femur: a rare entity with diagnostic dilemma

Abstract

Clear cell chondrosarcoma is an extremely rare malignant neoplasm. The rarity and slow-growing nature of this tumour often lead to prolonged symptoms and also initial misdiagnosis with benign lesions such as chondroblastoma. It can also be confused with avascular necrosis of the femoral head when the lesion is located in the femoral head, as was in the case we report. The patient was kept on observation and conservative treatment for almost 9 years before the correct diagnosis and appropriate treatment. Wide local resection with negative margins forms the mainstay of treatment since intralesional procedures predispose to high local recurrence rate. A prolonged follow-up is recommended since late local recurrences and metastases are common.
