Final Diagnosis

Cytology

  • Follicular neoplasm.


Discussion

The diagnostic criteria for follicular lesions are based on cellularity and the presence of colloid. Follicular lesions will be cellular with an absence of the variability in the size of the follicular groups, with a predominately microfollicular pattern. Colloid will be scant to absent, except for the presence of inspissated colloid in the center of follicular groups. There is often a disorganized, crowded follicular pattern with some nucleomegaly and nucleoli.
