Benign pathology included goiter, Hashimoto’s thyroiditis, thyroid cyst, hyperplastic nodules, and Hurthe cell adenomas associated with papillary thyroid microcarcinoma. Malignant pathology (confirmed or suspected) was based on fine needle aspiration biopsy of nodules or pre-operative imaging. All cases with confirmed malignancy pre-operatively were papillary thyroid cancer
