Malignant transformation to synovial chondrosarcoma. This is a very rare complication occurring in chronic cases. Treatment entails synovial excision and total joint replacement. [citation needed] Clicking, grating, or locking may result from acute mechanical problems due to intra-articular bodies within the affected joint. Locking may destroy ...
Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy. Unlike other primary ...
Osteosarcoma tends to affect regions around the knee in 60% of cases, 15% around the hip, 10% at the shoulder, and 8% in the jaw. The tumor is solid, hard, irregular ("fir-tree," "moth-eaten", or "sun-burst" appearance on X-ray examination) due to the tumor spicules of calcified bone radiating at right angles.
A chondrosarcoma is the type of bone cancer that starts in the cartilage cells. It is the most common type found in adults. Unlike the other types it is rarely found in those under the age of twenty. Most chondrosarcomas develop in the pelvis, legs or arms. Benign counterparts are known as enchondromas. Chondrosarcomas are classified by grade ...
EMC was firstly described in 1953 by Stout et al. when they discussed the different species of extraskeletal chondrosarcoma, [2] but EMC concept was firstly proposed in 1972 by Enzinger et al. [3] Brody thought that this was a unique low-grade malignancy with a low growth rate and both clinically and histopathologically distinct anamnesis beside the typical chondrosarcomas. [4]
Hereditary multiple osteochondromas (HMO), also known as hereditary multiple exostoses, is a disorder characterized by the development of multiple benign osteocartilaginous masses in relation to the ends of long bones of the lower limbs such as the femurs and tibias and of the upper limbs such as the humeri and forearm bones.
The aircraft, flown by Boom’s chief test pilot Tristan “Geppetto” Brandenburg, accelerated to Mach 1.1 for the first time (around 844 miles per hour / 1,358 kilometers per hour) — 10% ...
Osteochondroma is the most common benign tumor of bone. [1] [2] The tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones ().[3] [4] It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone.
