Specimen: US-guided thyroid FNA, left lobe nodule (TIRADS 4a, 12.1*8*11.2 mm).

Radiologic diagnosis: R/O benign versus malignancy.

Macroscopy: Received 5 alcohol-fixed & 1 air-dried slides.

Microscopy: All received slides were examined & showed moderately cellular smears. Along with monolayer clusters of almost unremarkable thyroid follicular epithelial cells, there are clusters with non-specific atypia mainly as fine chromatin pattern & nuclear overlapping as well as a few nuclear grooves. Many isolated nuclei or mature lymphocytes & modest amount of colloid are also seen in a bloody background.

Interpretation: Thyroid nodule, left lobe, FNA-Cytology:

- Atypia of undetermined significance (Bethesda III).

Comment: Repeat of FNA after appropriate interval is recommended.
