Abstract
|
|
|
Ectopic thyroid is known to be a very rare disease. Its prevalence is 1 in 100,000-300,000, and it is the most common form of thyroid dysgenesis. In addition, it is known that primary thyroid cancer arising from ectopic thyroid tissue is rare. A 41-year-old male patient with mass in the anterior of the neck was admitted to our department of Otolaryngology. A surgical excision of the neck mass was carried out and the histopathology revealed papillary thyroid carcinoma. Total thyroidectomy and bilateral central neck dissection were then performed after 3 months from previous operation. As a result of histopathologic examination after surgery, we incidentally identified papillary microcarcinoma in the right thyroid lobe. We report a case of ectopic thyroid papillary carcinoma with incidental papillary thyroid microcarcinoma with a literature review.
