Overview

The other diagnostic studies available for pleomorphic adenoma are FNA and core biopsy.

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:
