Adequacy
A minimum number of 6 clusters with 10 cells each has been arbitrary established to assume adequacy for a definitive diagnosis.[1] The presence of characteristic cells may still confer a definitive diagnosis, but otherwise, the report will simply state inadequate number of cells.
Risk stratification
Classify findings as per the Bethesda system:
Category | Description[2] | Example report |
---|---|---|
I | Non diagnostic/unsatisfactory | |
II | Benign (colloid and follicular cells) | Thyroid aspiration, right upper pole:
|
III | Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS) (follicular or lymphoid cells with atypical features) | Thyroid aspiration, right mid pole:
|
IV | Follicular nodule/suspicious follicular nodule (cell crowding, micro follicles, dispersed isolated cells, scant colloid) | |
V | Suspicious for malignancy | |
VI | Malignant |
