Clear-cell chondrosarcoma of the humerus
Radiology Case Reports
|June 23, 2016
Summary
Clear-cell chondrosarcoma, typically slow-growing, can exhibit aggressive behavior with early metastasis. This case highlights the need for vigilant monitoring and early detection of recurrence and spread in patients.
Area of Science:
- Orthopedic Oncology
- Skeletal Radiology
- Pathology
Background:
- Clear-cell chondrosarcoma is a rare, low-grade bone sarcoma.
- It typically presents with slow growth and low metastatic potential.
- Local recurrence is common even after treatment.
Observation:
- An unusual case of clear-cell chondrosarcoma of the humerus demonstrated aggressive behavior.
- This aggressive variant led to early metastasis to multiple distant bone sites.
- Metastatic sites included the femur, spine, sacrum, and iliac bone.
Findings:
- The aggressive clear-cell chondrosarcoma presented with rapid, widespread bony metastasis.
- Imaging and histological features may aid in identifying aggressive subtypes.
- Early detection of recurrence and metastasis is crucial.
Implications:
- Physicians must be aware of the potential for aggressive clear-cell chondrosarcoma behavior.
- Closer and more frequent follow-up is necessary for early detection.
- Prompt treatment of recurrence and metastasis can improve outcomes.

01:19Bones of the Upper Limb: Humerus
13.3K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:27Growth of Cartilage and Bone Tissue
4.6K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

01:24Bone Formation by Endochondral Ossification
11.7K
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...
