Abstract

An ectopic thyroid tissue is often localized in the midline between the foramen caecum and mediastinum, while it is rarely laterally localized. Submandibular location of thyroid tissue is extremely rare. In this article, we report a 56-year-old female case admitted with a painless, non-tender, and firm mass in the right submandibular region. The patient was operated. The mass was detected to be separate from the right lobe of the thyroid. The histopathological examination result was reported as an ectopic thyroid tissue. Ectopic thyroid tissues should be considered in the differential diagnosis of submandibular masses.

Submandibüler bölge yerleşimli ektopik tiroid dokusu

Abstract

Ektopik tiroid dokusu çoğunlukla foramen çekum ile mediasten arasında orta hatta olup, nadiren lateral yerleşimlidir. Submandibüler yerleşimli tiroid dokusu oldukça nadirdir. Bu yazıda, sağ submandibüler bölgede ağrısız, hassasiyeti olmayan ve sert bir kitle nedeniyle başvuran 56 yaşında bir kadın olgu sunuldu. Olguya cerrahi yapıldı. Kitlenin sağ tiroid lobu ile ilişkili olmadığı gözlendi. Histopatolojik inceleme sonucu, ektopik tiroid dokusu olarak bildirildi. Submandibüler kitlelerinin ayırıcı tanısında ektopik tiroid dokusu akla getirilmelidir
