<p><strong>Context: </strong>In adults, non-invasive follicular variant papillary thyroid carcinoma (FVPTC) is considered low risk for metastasis and persistent/recurrent disease.</p>

<p><strong>Objective: </strong>The goal of this study was to assess the clinical, sonographic, and histopathological features of FVPTC in a pediatric cohort.</p>

<p><strong>Design: </strong>A retrospective review of subjects &lt; 19 years of age with papillary thyroid carcinoma (PTC) who underwent thyroidectomy between January 2010 and July 2015.</p>

<p><strong>Setting: </strong>Multidisciplinary, academic referral center.</p>

<p><strong>Patients: </strong>Patients with FVPTC, defined as a tumor ≥1.0 cm in largest dimension with predominant follicular growth, complete lack of well-formed papillae, and nuclear features of PTC.</p>

<p><strong>Main Outcome Measure: </strong>Tumor size and location, presence of a tumor capsule, capsule and vascular invasion, lymph node and distant metastasis.</p>

<p><strong>Results: </strong>Eighteen patients with FVPTC were identified from a case cohort of 110 patients with PTC. On histopathology, 13 (72%) had unifocal nodules and 14 (78%) were completely encapsulated. Capsule invasion was frequent (9/14; 64%) and vascular invasion was found in one third of patients (6/18; 33%). No lymph node metastases were found in the 13 (72%) patients who had a central neck lymph node dissection. One patient with vascular invasion had distant metastases.</p>

<p><strong>Conclusion: </strong>When strictly defined, FVPTC in pediatric patients has a low risk for bilateral disease and metastasis. Prospective studies are needed to confirm whether lobectomy with surveillance is sufficient to achieve remission in pediatric patients with low risk FVPTC.</p>
