What is bottle 2073?
2073 Knee: Arthritis - pseudogout calcium pyrophosphate deposition
What is bottle 267?
**267 Femoral head - Osteoarthritis
**
**Radiological signs of osteoarthritis
**
* Irregular joint space narrowing
* Subchondral sclerosis: a dense area of bone (visible on x-ray) just below the cartilage zone of a joint that forms as a result of a compressive load on the joint
* Osteophytes (bone spurs): spurs or densifications that develop on the edges of the joint, increasing its surface area
* Subchondral cyst: a fluid-filled cyst that develops on the surface of a joint due to local bone necrosis induced by the joint stress caused by osteoarthritis

Synoyvium: pigmented villonodular synovitis
Pigmented villonodular synovitis (PVNS) is a condition that causes the synovium—the thin layer of tissue that lines the joints and tendons—to thicken and overgrow. The mass or tumor that results from this overgrowth is not cancerous and does not spread (metastasize) to other areas of the body.

Cut surface of the humerus demonstrates multi-lobulated endomedullary lesions, bluish-white, homogenous and glistening in appearance consistent with hyaline cartilage. There is no extension through cortex.

228 Femur: Malignant fibrous histiocytoma
228 Femur: Malignant fibrous histiocytoma
Malignant Fibrous Histiocytoma (MFH) usually arises in soft tissue and is typically a malignant soft tissue sarcoma, but may arise from bone in 1% to 5% of all cases and accounts for 3% to 8% of all bone tumors. In this case it is called MFH of Bone. It is a rare tumor. It can occur in patients ranging from 10 to 60 years old, the largest number occurred in the second decade.
