cytology, thyroid nodules

The aim of our study was to assess the accuracy and limitations of ultrasound guided fine-needle aspiration cytology (FNAC) of thyroid nodules. METH.S: The usg-FNAC results of 245 patients with thyroid nodules, who afterwards underwent thyroid surgery or who died, and autopsies were carried out, and compared retrospectively with cytologic results. Patients with malignant cytologic conclusion without histological confirmation after surgery or autopsy were excluded from the study (9 persons). The usg-FNAC results were divided as follows: group 1: diagnosis of malignancy (n = 30), group 2: suspicion of malignancy (n = 28), group 3: benign (n = 126), group 4: inconclusive (n = 29).
