Other Diagnostic Studies
Other Diagnostic Studies
- Pleomorphic adenoma may also be diagnosed using fine needle aspiration (FNA) and core needle biopsy.
- FNA can determine whether the tumor is malignant in nature with a sensitivity approximately 90%[1]
- FNA can also distinguish primary salivary tumor from metastatic disease.
- Core needle biopsy is more accurate compared to FNA with diagnostic accuracy greater than 97%[2]
- Findings on fine needle aspiration (FNA) and core needle biopsy, include:
- Admixture of polygonal epithelial and spindle-shaped myoepithelial elements
- Mesenchymal stroma (important feature)
- Proliferation of myoepithelium and epithelium
