Follicular neoplasm of the thyroid gland: unique cytologic appearances in a fine-needle aspiration biopsy.

摘要

Fine-needle aspiration (FNA) biopsy has become a standard first-line diagnostic procedure for palpable and nonpalpable nodules of the thyroid gland. Six cytologic diagnostic categories have recently been proposed to unify the terminology that is linked to proper clinical management. We report a case of follicular neoplasm diagnosed on FNA specimen that had a very artistic appearance of the microfollicle formation on both Diff-Quik and Papanicolaou-stained slides.
