Abstract
Lingual thyroid (LT) is a developmental defect due to the failure of the thyroid gland to descend to its normal cervical location during embryogenesis. Lingual thyroid has an overall prevalence of 1 in 100,000 to 1in 3,00,000 and is seven to ten times more common in females than in males .Lingual position represents the most frequent ectopic location accounting up to 90% of ectopic cases. It is found at the junction of the anterior two thirds and the posterior third, between the epiglottis and the circumvallate papillae. Most cases are asymptomatic, however, increase in size can cause local symptoms like upper airway obstruction, dysphagia and hemorrhage at any time from infancy to adulthood. Thyroid scintigraphy, neck ultrasound, CT- scan, MRI are some diagnostic modalities that play a vital role in diagnosing ectopic thyroid gland. Treatment of this anomaly includes exogenous L-thyroxine hormone administration, radioiodine ablation therapy and surgery. We hereby report a rare case of lingual thyroid in a young girl reported by fine needle aspiration cytology.
