Summary
This case report details a rare primary intramedullary chondrosarcoma of the proximal humerus in a 60-year-old female. Surgical resection and reconstruction were successfully performed for this bone tumor.
Area of Science:
- Orthopedic Oncology
- Musculoskeletal Radiology
- Surgical Pathology
Background:
- Primary chondrosarcoma is a rare bone malignancy, ranking third after myeloma and osteosarcoma.
- These tumors exhibit variable growth rates, from slow-growing to highly aggressive.
- Intramedullary chondrosarcoma of the proximal humerus is an uncommon presentation.
Purpose of the Study:
- To report a unique case of primary intramedullary chondrosarcoma affecting the proximal humerus.
- To illustrate the diagnostic imaging findings and histopathological confirmation of this rare bone tumor.
- To describe the surgical management and reconstruction approach for this specific tumor location.
Main Methods:
- A 60-year-old female patient presented with arm pain and swelling.
- Diagnostic imaging included radiography, computed tomography (CT), magnetic resonance imaging (MRI), and bone scan.
- Histopathological examination confirmed the diagnosis, followed by wide surgical resection and endoprosthetic reconstruction.
Main Results:
- Radiography revealed an expansile intramedullary lesion with calcification and a soft tissue mass.
- CT confirmed the lesion's characteristics; MRI showed a lobulated, hyperintense T2WI mass with fibrous septae.
- Bone scan indicated increased tracer uptake; histopathology confirmed chondrosarcoma.
Conclusions:
- Primary intramedullary chondrosarcoma of the proximal humerus is a rare entity requiring accurate diagnosis.
- Multimodality imaging plays a crucial role in characterizing these bone tumors.
- Wide resection and endoprosthetic reconstruction represent a viable surgical strategy for this condition.

01:19Bones of the Upper Limb: Humerus
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...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
