Skeletal metastasis: the effect on the immature skeleton
Skeletal Radiology
|January 1, 1982
Summary
Metastatic angiosarcoma in a child extensively affected the appendicular skeleton, particularly the metaphysis. This pattern suggests arterial hematogenous spread, similar to osteomyelitis, leading to fractures and growth plate injuries.
Area of Science:
- Pediatric oncology
- Skeletal pathology
- Radiology
Background:
- Metastatic angiosarcoma is a rare pediatric malignancy.
- Understanding skeletal involvement patterns is crucial for diagnosis and treatment.
Purpose of the Study:
- To detail the radiographic and pathological findings of appendicular skeletal involvement in a child with metastatic angiosarcoma.
- To investigate the pattern and mechanism of bone metastasis in pediatric angiosarcoma.
Main Methods:
- Detailed radiographic assessment of the entire appendicular skeleton.
- Pathological examination of metastatic lesions within the bone.
- Analysis of fracture patterns and growth plate involvement.
Main Results:
- Widespread metastatic disease was observed throughout the appendicular skeleton, with variable extent.
- The metaphysis was the most common site of metastasis, exhibiting a distinct pattern of bone destruction.
- Metaphyseal fractures and physeal separation occurred, indicative of pathological bone weakening.
Conclusions:
- Metaphyseal metastatic spread in pediatric angiosarcoma likely occurs via arterial hematogenous dissemination.
- The unique bone structure in children influences the radiographic appearance and progression of skeletal metastases.
- Findings support similarities between metaphyseal metastasis and osteomyelitis in children.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:22The Functions of the Skeletal System
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
