Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

14.6K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Classification of Bones

14.3K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Tumor Progression02:07

Tumor Progression

6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

14.3K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Area of Science:

  • Orthopedic Oncology
  • Skeletal Pathology
  • Tumor Histology

Background:

  • Osteosarcoma is the most common primary malignant bone tumor, typically affecting the metaphysis of long bones.
  • Diaphyseal osteosarcoma represents a rare subtype, accounting for approximately 10% of all osteosarcoma cases.
  • Osteosarcoma exhibits significant diversity in histologic features and tumor grade.

Observation:

  • A case of a 29-year-old male with diaphyseal osteosarcoma of the left tibia is presented.
  • The patient reported pain and swelling in the middle third of the left leg.
  • Biopsy of the tibial lesion revealed varied histomorphologic features within the examined tissue.

Findings:

  • The presented case underscores the heterogeneity of diaphyseal osteosarcoma.
  • Varied histomorphologic patterns were observed in the biopsy, emphasizing the complexity of osteosarcoma classification.
  • Accurate histologic assessment is crucial for understanding the diverse nature of this bone tumor.

Implications:

  • Reporting diverse histologic patterns aids in the accurate diagnosis and classification of diaphyseal osteosarcoma.
  • Understanding the histomorphologic variability is essential for guiding treatment strategies and predicting prognosis.
  • This case contributes to the literature on rare osteosarcoma subtypes, informing future research and clinical practice.
