Diferansiye tiroit karsinomlu olgularda nadir bir tanısal yanılgı sebebi: Lateral servikal ektopik tiroit
Abstract
Ektopik tiroit genellikle boyun orta hatta izlenmekle birlikte, nadir olarak lateral yerleşimli de olabilir. Bu çalışmada diferansiye tiroit karsinomu nedeniyle total tiroidektomi uygulanan ve lateral ektopik tiroit dokusu saptanan 4 olgu sunulmaktadır. Operasyon sonrası evreleme için Tc99m perteknetat ile yapılan sintigrafi incelmesinde olguların 3’ünde submandibuler bölgede artmış tutulum izlenen alanda, ultrasonografik incelmede tiroit bezi ile eş ekojenite homojen iç yapıda ektopik tiroit dokusu saptanırken, diğer olguda alt juguler bölgede izlenen heterojen iç yapıda nodüler lezyon, yapılan santral-lateral boyun diseksiyonu sonucunda ektopik tiroit dokusu tanısı almıştır. Metastatik lenf bezi ile primer lateral ektopik tiroit dokusu ayrımı primer tiroit karsinomlu olgularda oldukça önemli olup, laboratuvar verileri, sintigrafi ve ultrasonografiyi içeren tanısal çalışma evrelemede kritik rol oynamaktadır. Oldukça nadir olmakla birlikte ektopik tiroit, lateral boyun kitlelerinin ayırıcı tanısında akılda bulundurulmalıdır.

A rare cause of diagnostic pitfall in cases with differentiated thyroid carcinoma: Lateral cervical ectopic thyroid
Abstract
Ectopic thyroid is usually detected in the midline of the neck; however, it may rarely be located laterally. In this study, 4 cases who underwent total thyroidectomy for differentiated thyroid carcinoma and were found to have lateral ectopic thyroid tissue are presented. In the Tc-99m pertechnetate scintigraphy examination performed for postoperative staging, 3 of the cases showed increased uptake in the submandibular region, and ultrasonographic examination revealed ectopic thyroid tissue with homogenous internal echotexture similar to the thyroid gland, while in the remaining case, the heterogeneous nodular lesion was observed in the lower jugular region, and as a result of central-lateral neck dissection, was diagnosed with ectopic thyroid tissue. Differentiating metastatic lymph nodes and primary lateral ectopic thyroid tissue is crucial in cases with primary thyroid carcinoma, and diagnostic workup, including laboratory data, scintigraphy, and ultrasonography, plays a critical role in staging. Although it is rare, ectopic thyroid should be kept in mind in the differential diagnosis of lateral neck masses.
