Abstract
Introduction: Thyroid nodules are common in clinical pathology practice and are the most common indication for thyroidectomies.
In the present study we evaluated patients diagnosed with nodular goiter according to preoperative thyroid fine needle aspiration
cytology and who also underwent thyroidectomy.
Materials and methods: The case reports, pathologic reports, and stained sections of 1149 patients who were admitted and
underwent thyroidectomy specimens were retrospectively evaluated.
Results: The cytology and histology records were correlated for 260 cases. The 1149 cases included in this study consisted of
1020 female and 129 male cases with a mean age of 41.4 years (range, 13 to 82 years). The distribution of histological findings are
as follows: 999 (72.3%) cases were found to be non-neoplastic and 150 cases (13.1%) were neoplastic. Postoperative histologic
evaluation demonstrated 939 (81.7%) cases of nodular hyperplasia, 70 (6.1%) cases of papillary carcinoma, 55 (4.8%) cases of
follicular adenoma, 39 (3.4%) cases of Hashimoto’s thyroiditis. The correlation of cytology and histopathology showed that 145 of
260 FNA results (55.7%) were concordant, whereas 8 patients (3%) had discordant results. Eighty-five cases were excluded for
being non-diagnostic. Histological review revealed incidental papillary thyroid carcinoma in 62 (5.39 %) patients. Mean tumor size
was 1.26 cm.
Conclusion: Nodular hyperplasia was the most common histopathological finding followed by papillary thyroid carcinoma.
Improved imaging techniques combined with the correct use of fine-needle aspiration diagnoses may reduce the number of cases
that are not treatable by thyroidectomy. It is likely that the early detection of some thyroid cancers is primarily incidental.
