Diffuse follicular variant papillary thyroid carcinoma (DFVPTC) is a rare variant papillary thyroid carcinoma. DFVPTC typically occurs in young females, extensively involves one lobe or both lobes entirely with frequent nodal metastasis and vascular invasion. In contrast to the other subtypes of follicular variant, DFVPTC has biologically aggressive behavior. We present a case of DFVPTC arising in a 69-yr-old male patient. He presented hoarseness for a few months. Following diagnosis of malignancy on aspiration cytology, total thyroidectomy with neck dissection was performed. The tumor involved both lobes of thyroid, encroaching the surrounding structures including tracheal cartilage and esophagus. Multiple lymph node metastasis and vascular invasion were also found. The patient passed away due to the unexplained bleeding of surgical site.
