Clear Cell Chondrosarcoma Arising in Hyoid Bone

ABSTRACT

Clear cell chondrosarcoma, first described by Unni in 1976, is distinguished from classical chondrosarcoma by a typical histological picture, mostly an epiphyseal site of origin, and relatively a benign clinical course. We present a case of clear cell chondrosarcoma arising from hyoid bone in a 70-year-old male. Histologically, large areas of closely packed cells with characteristic clear cytoplasm were seen in addition to the usual elements of a conventional chondrosarcoma. Our search and review of the literature did not reveal any reported case of clear cell chondrosarcoma arising from hyoid bone.
