Methods

We performed a retrospective data collection and analysis from patients diagnosed with LT at Mayo Clinic, Rochester, Minnesota, between 1976 and 2010. A search for the terms "lingual thyroid" and "ectopic thyroid" was performed using the Data Discovery and Query Builder in the Mayo Clinic Life Sciences System database. Fifty patients were identified with this strategy. We reviewed each case and excluded patients with thyroglossal cyst, substernal thyroid, mediastinal thyroid, or lingual tonsil. Electronic medical records were available after 2001; archived paper charts were reviewed for patients seen between 1976 and 2001. The study was approved by the Mayo Clinic Institutional Review Board.

The following information was collected from each participant: gender, age at diagnosis, method of diagnosis, presence/absence of other thyroid tissue, symptomatology, comorbidities, thyroid function tests, treatment, and outcomes of the chosen management.

We also performed a literature review of LT cases published between 1965 and 2015. All reports of a minimum of 2 cases were included. The search was performed by a specialized librarian (Philip D. Walker) using PubMed.
