Chordoid sarcoma: ultrastructural evidence supporting a synovial origin.
Cancer
|February 1, 1980
Summary
This study details a rare chordoid sarcoma case in a 72-year-old man. Ultrastructural analysis suggests a synovial origin for this hand tumor.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Chordoid sarcoma is a rare soft tissue neoplasm.
- This study presents a unique case of chordoid sarcoma on the dorsum of the right hand.
Observation:
- The tumor exhibited lobular architecture with epithelioid and clear cells at the periphery.
- Stellate and spindle-shaped cells formed a characteristic "cobweb" pattern in a loose matrix.
- Microscopic examination revealed pseudoacinar formation, microvilli, and cytoplasmic filaments.
Findings:
- Electron microscopy identified distinctive ultrastructural features, including numerous desmosomes and partial basal lamina.
- The observed ultrastructure supports a synovial origin for this uncommon chordoid sarcoma.
- Key features included long cytoplasmic filopodia with complex interdigitations.
Implications:
- Understanding the ultrastructural characteristics aids in accurate diagnosis of chordoid sarcoma.
- This case contributes to the literature on rare soft tissue tumors.
- The findings may inform future research into the pathogenesis and treatment of synovial sarcomas.

01:27Growth of Cartilage and Bone Tissue
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...
01:17Structural Joints: Cartilaginous Joints
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...

01:16Structural Joints: Synovial Joints
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
01:07Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:24Bone Formation by Endochondral Ossification
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...
01:13Microscopic Anatomy of Skeletal Muscles
Skeletal muscle cells, also called muscle fibers, are distinctly elongated, multi-nucleated, slender biological units. They are packed with specialized structures designed to facilitate their primary function, which is contraction.
The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...
