| Summary: | INTRODUCTION: Thyroid cancers are the most common endocrine tissue malignancies. In recent years, it has been increasingly seen in childhood throughout the world. The aim of this study was to investigate the effect of thyroid nodule volume, diameter and multicentricity on malignancy in patients undergoing surgical procedures in our clinic. METHODS: A total of 20 pediatric patients aged 1-17 years who underwent total thyroidectomy and / or lobectomy for thyroid nodule between 2014-2019 were evaluated. The effect of age, sex, nodule diameter, volume and multicentricity in the patients were examined on malignity retrospectively. RESULTS: The study patients were 15 female and 5 male. The mean age of the patients was 14 years, nodule diameter was 3 cm in malignancies and 2 cm in benign tumors, while nodal volume was 7.8 cm3 in both malignant and benign patients. According to the pathology results after surgery, multicentricity was present in nine patients. Seven of the these nine patients were malignant and two were benign. DISCUSSION AND CONCLUSION: High nodule diameter, volume and multicentricity did not increase risk of malignancy. Therefore, we concluded that the diameter, volume and multicentricity of the nodule cannot be used to predict malignancy or to decide surgical resection.
