Summary
Solid Variant of Aneurysmal Bone Cyst (SVABC) is a rare bone neoplasm often misdiagnosed as malignant. Accurate diagnosis is crucial to avoid unnecessary aggressive treatments.
Area of Science:
- Orthopedic Oncology
- Pediatric Pathology
- Skeletal Radiology
Background:
- Solid Variant of Aneurysmal Bone Cyst (SVABC) is an uncommon bone neoplasm.
- It frequently mimics malignant bone tumors clinically and radiologically.
- SVABC typically affects young patients and long bones.
Observation:
- Two cases of SVABC presented as expansile, osteolytic lesions with cortical destruction.
- Both cases were initially misdiagnosed as osteosarcoma.
- The lesions were located in the long bones.
Findings:
- Radiological features included expansile osteolytic lesions with cortical breach.
- Histopathological correlation is essential for accurate diagnosis.
- SVABC shares aggressive radiographic features with malignant bone tumors.
Implications:
- Accurate diagnosis of SVABC is critical to alter treatment strategies.
- Avoiding misdiagnosis prevents unnecessary mutilating surgeries.
- Preventing unnecessary chemo-radiotherapy improves patient outcomes.

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:09Spongy Bone

All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:29Bone Disorders
5.6K
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...

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...

01:29Bone Formation by Intramembranous Ossification
11.7K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

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.
