[A pathologist's thoughts on the cytological diagnosis of thyroid neoplasias]

Terminological and classification aspects are of great importance in the systems approach to managing endocrinological patients, including those with thyroid cancer. The 2007 Bethesda (USA) thyroid cytological study classification system contributes to the improvement of patient selection results for surgery for cancer evidence. Experience with more than 120000 cytological studies and more than 4500 examinations of intraoperative thyroid specimens could reveal some gap between the cytological interpretation of thyroid pathology and the evaluation of individual morphological phenomena that are particularly important in the differential diagnosis of follicular neoplasias, rare variants of papillary carcinoma. Among other things, there was evidence that it was inexpedient to use the term "dysplasia" in relation to the follicular epithelium and in both cytological and histological practice. Analysis of the results of consultations could reveal the most common diagnostic errors during morphological studies.
