Summary
Fine needle aspiration cytology effectively diagnosed osteosarcomas in 59 cases. Recognizing diverse osteosarcoma morphologies is crucial for accurate diagnosis and avoiding misinterpretation.
Area of Science:
- Oncology
- Cytopathology
- Orthopedic Oncology
Background:
- Osteosarcoma is a primary malignant bone tumor.
- Accurate cytological diagnosis is essential for effective treatment planning.
Purpose of the Study:
- To evaluate the utility of fine needle aspiration cytology (FNAC) in diagnosing osteosarcoma.
- To identify the diverse cytological appearances of osteosarcoma.
Main Methods:
- Retrospective analysis of 63 clinically and radiologically diagnosed osteosarcoma cases.
- Fine needle aspiration cytology was performed on 59 adequate samples.
- Morphological classification included pleomorphic, sclerotic, chondroid, and small cell types.
Main Results:
- The mean age of patients was 16 years.
- Pleomorphic osteosarcoma was the most frequent type (42 cases).
- Hematoxylin and Eosin stain demonstrated superior osteoid detection compared to routine stains.
Conclusions:
- FNAC is a valuable tool for diagnosing osteosarcoma.
- Awareness of cytological diversity is critical to prevent misdiagnosis.
- Optimized staining techniques can improve diagnostic accuracy.
