Objective Differentiated thyroid cancer (DTC) is rare in the pediatric population, with most data from the Western world. We aimed to describe the clinical presentation, treatment intervention, histopathological characteristics, complications, follow-up, and response to treatment in 17 patients with DTC at or below the age of 20 years. Interventions This was a retrospective cohort study at King Abdulaziz Medical City, Jeddah, Saudi Arabia. We included patients aged younger than 20 years with DTC. Total or near-total thyroidectomy was performed in 82% of the patients, central and/or lateral neck dissection in 35% of cases, and radioactive iodine (RAI) ablation in 76% of cases. Results The study included 17 patients (14 females), with a median age of 16 years at the time of diagnosis. Thyroid nodules were the main complaint in 88% of the patients. Thyroid ultrasonography was the main method for the initial evaluation. Papillary cancer was the most common type of tumor, and lymph node spread was found in 82% of the patients. Moreover, 40% of the patients exhibited excellent responses to therapy, with 35% showing indeterminate results. Only 23.5% of the patients developed hypocalcemia postoperatively. Conclusions Classical papillary thyroid carcinoma was the predominant histopathological type, and most patients showed excellent responses to therapy, followed by indeterminate in most of the cases. The most common presentation was a neck nodule, signifying the role of thorough physical neck examinations. Finally, recurrence occurred in a minority of patients. However, none of these patients died.
