References Chondrosarcoma secondary to enchondroma is a primary neoplasm of cartilaginous histogenesis arising from a pre-existing benign enchondroma. Age: 30 - 50 Site: The most common precursor is multiple enchondroma or Ollier's disease. This phenomenon is rare in solitary enchondroma or synovial chondromatosis. The patient presents with pain at the site of a previously-painless enchondroma. Slow, displacing growth is characteristic of this tumor with very late transition to a high-grade lesion and risk of metastasis. The survival rate is excellent with adequate treatment prior to transition. On radiograph, there is an expanding, radiolucent zone surrounding a calcified enchondroma with endosteal scalloping and periosteal, cortical thickening. [X-Ray] This radiograph shows the original enchondroma at first presentation. The patient was asymptomatic at this time. [X-Ray] This radiograph was made fourteen years later when the patient presented with a secondary chondrosarcoma.

Extractions: Francesco Guerreschi, MD, Lecco, ITALY Seventeen limb segments representing eight femora, six tibia and three humeri in nine patients with Ollier's disease were treated using the Ilizarov method. The mean lengthening achieved was 7.0 cm in the femur, 6.8 cm in the tibia and 7.5 cm in the humerus. The average duration of treatment was 7.5 months. Equal limb length was achieved in six of seven lower limbs. Multiplanar angular deformities were corrected in all the limb segments. With a mean follow-up of 4.3 years, the tissue transformation and corrections achieved are observed to be maintained. The corticotomy and tissue manipulation through the sites of the lesions achieved angular correction and lengthening and tissue transformation of the lesions. Moderator(s):Henry J.

Metabolic Disease Osteoporosis Rickets/Osteomalacia Hyperparathyroidism This condition results from excessive PTH release. The primary form results from hyperplastic parathyroid tissue. The secondary form is typically a consequence of renal failure. Unchecked PTH release stimulates osteoclasts to resorb bone. Patients suffer from changes ocurring in bone and from the hypercalcemia that develops. Clinical: Osteitis fibrosa cystica Brown tumor Hypercalcemia Pathologic fractures

Extractions: Figure 2: Corresponding macro-slice showing a lobular architecture, and endosteal cortical thinning. Cytonucle ar appearance can be more readily appreciated in figure 3 Classification Note approximately 90% of chondrosarcomas are histologically of the conventional type; in addition to conventional chondrosarcoma, some rare variants with distinctive microscopic and clinical features are discerned: clear cell chondrosarcoma (1%), mesenchymal chondrosarcoma (2%), juxtacortical chondrosarcoma (2%) and extra-skeletal myxoid chondrosarcoma (5%). Furthermore, dedifferentiated chondrosarcoma is a relatively rare high grade sarcoma next to a low-grade conventional malignant cartilage-forming tumor, comprising 6-10% of all chondrosarcomas. Conventional chondrosarcomas can be categorized according to their location in bone. The majority of chondrosarcomas (75%) are located centrally within the medullary cavity (central chondrosarcoma), a small percentage of which arise within a preexisting benign precursor (enchondroma). While most enchondromas are solitary, patients with Ollier's disease and Maffucci's syndrome demonstrate multiple enchondromas.A minority (15%) of chondrosarcomas develops from the surface of bone (peripheral chondrosarcoma) as a result of malignant transformation within the cartilaginous cap of a solitary or hereditary pre-existent osteochondroma.

Extractions: Home Genes Leukemias Solid Tumours ... NA Identity Note Chondroma is an uncommon benign tumour which characteristically forms mature cartilage. It is found mostly in the small bones of the hand and/or feet, although it can also occur in long, tubular bones, primarily the humerus, femur and ribs. Occasionally, focal areas of mixoid degeneration may result in a mistaken diagnosis of chondrosarcoma. Classification Chondromas are classified according to their location: enchondroma: within the bone (within the medullary cavity), periosteal chondroma: on the surface of the bone, soft tissue chondroma in the soft tissue. Clinics and Pathology Disease Enchondroma Note Fig: Enchondroma in the distal portion of the femur shaft. (courtesy of Dr Henry DeGroot at http://www.drdegroot.com Enchondroma is usually a solitary benign lesion in intramedullary bone. Usually asymptomatic, it is incidentally discovered as a palpable bony nodule. Rarely, causes soft tissue swelling and pain at the lesion site. Pain can be a sign of pathologic fracture. Both sex are equally affected, and any age group can be involved. It is thought to develop from epiphyseal cartilage rests that subsequently proliferate and slowly enlarge. Approximately 50% of solitary enchondromas are found in the hands, typically in the middle and distal portions of the metacarpals and the proximal portions of the phalanges, 10% in the feet, 20% in the proximal and distal parts of the femur and the proximal part of the humerus.

DUPONT INSTITUTE WILMINGTON, DELAWARE CASE HISTORY: History : The patient is a 14 + 6 year old black male with a one year history of progressively worsening left knee pain. He states that the pain began in both knees and was intermittent, Tylenol helped alleviate the pain. Over the past 6 months the pain is more isolated to the left knee and has become constant in nature. Within the last 2 weeks the constant pain has become bad enough to limit his activities. He is unable to attend school or walk more than several hundred feet because of the pain. The pain is now affecting his sleep. He does get some relief with rest and elevation of the knee. The pain also limits his motion in that knee. He denies any trauma to the knee and has no other medical problems. He is not taking any medications. There is no family history of leg deformities. Physical Exam : The adolescent is a morbidly obese 14 + 6 year old black male. His extremity exam reveals an asymmetric pelvis with the right being elevated. There is a leg length inequality with the left leg being about 3.5 cm shorter than the right. He also demonstrates a significant proximal tibia vara of about 35
