Clear cell chondrosarcoma is a rare chondrosarcoma variant often involving the long bone epiphyses of young to middle aged adults. We report herein a case involving the left femoral head in a 25-year-old female with a 3-month history of worsening left hip pain. Radiographs revealed a complex, multifocal and lytic lesion centered in the left proximal femoral epiphysis with involvement of the femoral neck. Computed tomography-guided fine needle aspiration biopsy with concomitant core needle biopsy was performed, and a diagnosis of clear cell chondrosarcoma was rendered. Cytologic smears revealed aggregates of matrix material accompanied by a population of mostly uniform spindled to epithelioid and histiocytoid cells, rarely accompanied by osteoclast-type giant cells. The patient underwent surgical resection with -total hip replacement, and subsequent pathologic examination confirmed the initial needle biopsy diagnosis. There has been no evidence of local recurrence or distant metastases with 3-years follow-up. To our knowledge, this is the first reported example of a primary clear cell chondrosarcoma initially evaluated by fine needle aspiration biopsy.
