Is fine needle aspiration cytology a useful diagnostic tool for granular cell tumors? A cytohistological review with emphasis on pitfalls

Conclusions: These results imply that FNA has utility in the diagnosis of GCT, and should be included in the differential diagnoses when cells with abundant granular cytoplasm are seen on cytology. Careful attention to cytologic atypia, signs of reactive changes, use of immunohistochemistry, and clinical correlation are helpful in arriving at a definite diagnosis on FNA cytology.
