Abstract:
Metastatic tumors involving the bones may derive from a number of visceral primary sites, and they can assume several histological appearances. In selected instances, diagnostic confusion with some primary bone tumors may eventuate, necessitating the use of adjunctive pathologic studies to reach a final interpretation. This review considers metastatic osseous neoplasms in the small-cell, large-polygonal-cell, and spindle-cell-pleomorphic microscopic categories. The use of immunohistology and molecular analysis to study such tumors is discussed.

Metastasis
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...
Metastasis
Bone Disorders
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...

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
