Left Thyroid, FNA: BENIGN, see comment. | |||
Note: | |||
The specimen has abundant colloid. The background consists of histiocytes in keeping with a cyst. The number of follicular cells falls below the typically desired threshold; however, the case is sufficient on the basis of the abundant colloid, as per the 2023 Bethesda System for Reporting Thyroid Cytopathology. The clinical impression is noted. | |||
