Abstract
Ectopic thyroid tissue has been found from the tongue to the diaphragm. The most common ectopic thyroid tissue has been found in the tongue, submandibular region, cervical lymph nodes, larynx, trachea, oesophagus, mediastinum, diaphragm and heart respectively. "Forgotten goiter" is an extremely rare disease which is defined as a mediastinal thyroid mass found after total thyroidectomy. In this case report, we discussed a 49 year-old female patient whose retrosternal ectopic thyroid tissue was detected by thyroid scintigraphy taken in postoperative period after total thyroidectomy performed with diagnosis of multinodular goiter. Papillary carcinoma was determined by the histopathological examination. Ectopic thyroid tissue was removed by performing sternotomy. We did not observe any postoperative surgical complications. 100 mCi dose of radioactive iodine was administered to the patient. Retrosternal ectopic thyroid tissue detected after total thyroidectomy is a rarely encountered condition. Therefore, retrosternal ectopic thyroid tissue existence should be definitely kept in mind in patients with no increase in thyroid stimulating hormone level after total thyroidectomy.
Özet
Ektopik tiroid dokusu, dilden diyaframa kadar bulunabilir. En yaygın olarak sırasıyla dil, submandibular bölge, servikal lenf nodları, larinks, trakea, özofagus, mediasten, diyafram ve kalpte bulunur. "Unutulmuş guatr" total tiroidektomi sonrası bulunan mediastinal tiroid dokusu olarak tanımlanan oldukça nadir görülen bir durumdur.Bu olgu sunumunda multinodüler guatr tanısı ile total tiroidektomi uyguladıktan sonra postoperatif dönemde çekilen tiroid sintigrafisinde retrosternal ektopik tiroid dokusu tespit edilen 49 yaşında kadın hasta tartışıldı. Histopatolojik incelemesinde papiller karsinom tespit edildi. Ektopik tiroid dokusu sternotomi uygulanarak çıkarıldı. Postoperatif herhangi bir komplikasyon izlenmedi.Hastaya 100 mCi radyoaktif iyot tedavisi uygulandı. Total tiroidektomi sonrası retrosternal ektopik doku tespit edilmesi oldukça nadir görülen durumdur. Bu nedenle total tiroidektomi sonrası tiroid stimülan hormon düzeyi yükselmeyen hastalarda retrosternal ektopik tiroid dokusu varlığı mutlaka akılda bulundurulmalıdır.
