[Ectopic thyroid tissue localized in submandibular region].
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.
