Thyroid follicular carcinoma, compose the 10∼25% of the thyroid carcinoma, has relatively good prognosis. However in case recurrence, the survival rate decreases up to 50%. After the thyroid lobectomy, thyroxine (T4) is usually prescribed to prevent recurrence in contralateral lobe. A-79-year-old man was underwent the right thyroid lobectomy at ten years ago, proven follicular adenoma in histopathology. He developed the right lower anterior neck mass 7 months ago, we performed right thyroid lobectomy and the final diagnosis was follicular adenocarcinoma. After the 3 weeks, left completion thyroidectomy and anterior compartment neck dissection was carried out. The probable causes of recurrence are remnant tissue in previous surgery, limited operation than lobectomy and tumor regrowth from isthmus. etc. When all’s said and done, we think that the follicular adenoma turn over carcinoma in the previous lobectomy site. To the best of our knowledge, such case has not been reported earlier.
