Right lobe: Hypocellular smears, suggestive of adenomatous goiter with Hurthle cell change.
Left lobe: Hurthle cell rich follicular lesion (atypia) of undetermined significance.
Comment: Since oncocytic cells & neoplastic cells of para-follicular cell origin are closely similar, to rule out MTC, assay for serum Calcitonin is recommended.
Cytologic findings in left lobe slides
Moderate to high cellularity
Cohesive & loosely cohesiveclusters
Few microfollicles
Isolated cells with finely granular cytoplasm & many binucleated form
