Metastasis02:30

Metastasis

5.4K
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...

Bone Disorders

8.0K
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...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
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...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Remodeling01:40

Bone Remodeling

34.4K
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.

Area of Science:

  • Oncology
  • Pathology
  • Skeletal System Neoplasms

Background:

  • Bone metastases originate from various visceral primary sites.
  • Metastatic osseous neoplasms present diverse histological appearances.
  • Diagnostic challenges arise due to histological overlap with primary bone tumors.

Purpose of the Study:

  • To review metastatic osseous neoplasms.
  • To categorize these tumors based on microscopic appearance.
  • To discuss the utility of adjunctive studies in diagnosis.

Main Methods:

  • Review of literature on metastatic bone tumors.
  • Categorization of metastatic osseous neoplasms into small-cell, large-polygonal-cell, and spindle-cell-pleomorphic types.
  • Discussion of immunohistology and molecular analysis.

Main Results:

  • Metastatic tumors to bone exhibit varied histological patterns.
  • Specific microscopic categories aid in classifying metastatic osseous neoplasms.
  • Immunohistochemistry and molecular techniques are crucial for accurate diagnosis.

Conclusions:

  • Accurate diagnosis of metastatic bone tumors requires careful histological assessment.
  • Adjunctive pathological studies, including immunohistochemistry and molecular analysis, are essential for differentiating metastatic from primary bone tumors.
