Clear cell chondrosarcoma (CCC) is an infrequent variant of chondrosarcoma
characterized by low grade of malignancy, propensity to arise in the epiphyseal area
of long bones, progressive clinical course and late methastasis. It is more frequent in
men than women with a extensive age range. Clinical features are non-specifics; the
most frequent symptom is long standing local pain, sometimes referred to the
adjacent joint. Histologically CCC is characterized by tumor cells with abundant clear
cytoplasm and round nuclei arranged in a lobulated growth pattern, and in some
cases confused with aneurismal bone cysts. Typically, the radiography shows a
geographic osteolytic area located in epimetaphysis or epiphysis with sclerotic and
well-defined margins. We present a case of epiphyseal femoral CCC, with surgical
treatment with preservation of the femoral head and clinical and radiological followup
for 5 years, without recurrences or methastasis.
