Myxoid liposarcoma. An ultrastructural study of two cases
American Journal of Clinical Pathology
|October 1, 1979
Summary
Myxoid liposarcomas share ultrastructural similarities with developing white adipose tissue. However, unique features like 60-Angstrom filaments and glycogen masses suggest distinct developmental pathways for this sarcoma.
Area of Science:
- Oncology
- Cell Biology
- Histopathology
Background:
- Myxoid liposarcoma is a soft tissue sarcoma.
- Understanding its cellular origins is crucial for diagnosis and treatment.
Observation:
- Two cases of myxoid liposarcoma were analyzed using light and electron microscopy.
- Ultrastructural examination focused on comparing tumor cells to developing adipose tissue.
Findings:
- Most ultrastructural features of myxoid liposarcoma resemble those of developing white adipose tissue.
- Distinctive features observed include aggregates of 60-Angstrom filaments and significant glycogen deposits.
Implications:
- These findings suggest a potential link between myxoid liposarcoma and adipose tissue development.
- The presence of atypical ultrastructural elements may indicate unique cellular differentiation or dedifferentiation processes.
