Clear cell chondrosarcoma--a report of 2 cases.

Clear cell chondrosarcoma is a form of chondrosarcoma that was first described by Unni in 1976. It is essentially a low-grade chondrosarcoma with many similar clinical, radiological and histological features as the more common chondrosarcomas. However, the distinguishing feature of this variant is in the presence of the characteristic clear cells histologically. We relate two such cases of clear cell chondrosarcoma in Singapore. A short discussion covering the incidence/prevalence of this tumour, its common presenting clinical, radiological and histological features follows. We also review the available world literature, highlight the salient and differentiating aspects of this particular tumour, and touch on its management and eventual prognosis.
