Objectives: The aim of this study is observing the clinicopathologic features of thyroid papillary microcarcinomas (PTMs) andcomparing these features with papillary thyroid carcinoma (PTC).Methods: A total of 86 surgically treated patients suffering from PTC were evaluated retrospectively. Group 1 (G1) included patients with a tumor 1 cm. The two groups were compared in termsof the preoperative thyroid-stimulating hormone (TSH) level, anti-thyroid peroxidase antibody (anti-TPO) and antithyroglobulinantibody (TgAb) values, multicentricity, the lymphovascular invasion rate, the presence of extrathyroidal extension, and centraland/or lateral lymph node metastasis.Results: There was no statistically significant difference observed between the groups in terms of the preoperative TSH level,anti-TPO, and TgAb values. The rate of multicentricity of the tumor in G2 was 66%, while it was 36% in G1 (p<0.001). The lymphovascular invasion rate in G1 was 14.2%, while it was 61% in G2 (p<0.001). The extrathyroidal extension rate of the tumor cells in G1was 21.4%, while it was 63.6% in G2 (p<0.001). The central lymph node metastasis rate in G2 was 38.6%, while it was 4.8% in G1(p<0.001). The lateral lymph node metastasis rate in G2 was 20.5%, while it was 0% in G1 (p<0.001).Conclusion: PTMs are generally associated with good prognostic factors with high survival rates. However, the risk factors such asmultifocality, extrathyroidal extension, and lymphovascular invasion increasing the recurrence risk are not rare in PTM. Thus, thepatients having these histopathological features of the tumor should be followed more carefully.
