Central Chondrosarcoma of the Appendicular Skeleton

Abstract

The characteristic radiographic and pathologic appearance of central chondrosarcoma of the long bones is presented. The proximal femoral shaft is the most frequent site of involvement followed by the humeral head and the proximal shaft. This lesion is frequently misdiagnosed, and in this series of 14 patients was frequently thought to be enchondroma. Due to the invasive nature of the lesion, local measures such as curettage are not adequate and disarticulation is frequently warranted.
