Camurati–Engelmann disease (CED) is a very rare autosomal dominant genetic disorder that causes characteristic anomalies in the skeleton. It is also known as progressive diaphyseal dysplasia. It is also known as progressive diaphyseal dysplasia.
Ollier disease is a rare sporadic nonhereditary skeletal disorder in which typically benign cartilaginous tumors (enchondromas) develop near the growth plate cartilage.. This is caused by cartilage rests that grow and reside within the metaphysis or diaphysis and eventually mineralize over time to form multiple enchondroma
The diaphysis (pl.: diaphyses) is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.
An osteosarcoma (OS) or osteogenic sarcoma (OGS) (or simply bone cancer) is a cancerous tumor in a bone.Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid.
Other causes of bone diseases include severe impacts/injuries and weakness in bones/bone loss. The effects of bone disorders will vary with disease. The effects can occur physically, mentally and financially as well as impact the individuals quality of life. Orthopaedic disorders can drastically affect an individual's functional ability.
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
Primary bone cancer is a type of sarcoma, a cancer that originates in bone, muscle, fibrous tissue, blood vessels, fat tissue, as well as some other tissues. [2] Primary bone cancer can arise in any of the 206 bones in the body but is mostly seen to originate the arms and the legs. [3] The most common cases are observed in children and young ...
Although this disease is like Camurati–Engelmann disease where there is also diaphyseal dysplasia, there are, however, reasons to differentiate between the two diseases. As mentioned earlier, both diseases affect diaphysis, but Ghosal hematodiaphyseal dysplasia, affects both the diaphysis, and metaphyses. [1]
