Chondrosarcoma of bone.

摘要: To The Editor: We read with interest "Chondrosarcoma of Bone: An Assessment Outcome," by Lee et al. (81-A: 326-338, March 1999). Their experience extending over twenty-two years is impressive and largely parallels our own experience, which we are currently reviewing. We completely agree their comments about the difficulty in grading chondroid tumors, note that some low-grade tumors study would have certainly been considered to be borderline malignancy. fully appreciate this group have, for past five years, designated them as CLUMPs, stands "cartilaginous lesions unknown malignant potential." This categorization will help us get idea future how these behave, but at present time follow-up insufficient able comment any certainty. We believe order a tumor central chondrosarcoma, it must demonstrate permeative growth on either biopsy specimen or resection specimen. define presence around three sides trabecula normal medullary bone. If feature present, then defined chondrosarcoma. leaves sizable portion cartilaginous may modestly cellular, focally myxoid, show mild nuclear …
