BACKGROUND: @entity11677 ( @entity11677 ) @entity189 occurs in about 1 to 2% of @entity11677 cysts. Preoperative diagnosis is difficult, and consensus on optimal treatment is lacking. METHODS: All @entity1 who underwent surgical treatment of a @entity11677 cyst at our institution, a tertiary centre, were reviewed and @entity189 was identified. Clinicopathologic and follow-up information was examined. RESULTS: Among the 139 @entity1 treated for @entity11677 cysts, 9 @entity1 (6.5%) had a @entity189 . All were @entity1377 . There was a female predominance, and the median age at diagnosis was 44 years. The median follow-up was 6.7 years. All @entity1 underwent a Sistrunk procedure. A total thyroidectomy was performed in eight of nine @entity1 . The median size of the @entity189 was 10 mm. Two @entity1 underwent therapeutic neck dissection at the time of the total thyroidectomy. Two @entity1 experienced a recurrence regionally on follow-up. Eight of nine @entity1 received radioactive @entity1496 therapy and suppressive doses of @entity1955 . CONCLUSIONS: Strong conclusions are difficult to draw owing to the rarity of the disease. However, management should be similar to that of @entity259 and based on risk group stratification. An ultrasound-guided fine-needle biopsy is a valuable test in every @entity1 with a suspicion of @entity11677 cyst. A diagnosis of @entity189 should prompt evaluation of the thyroid gland and cervical lymph nodes bilaterally. A Sistrunk procedure is the minimum therapeutic procedure, coupled with a total thyroidectomy for higher-risk @entity5 .
