Lingual Thyroid Causing Dysphagia: A Case Report and Review of Literature
ثبت نشده
چکیده
Introduction: Lingual thyroid is the presence of thyroid tissue in the midline anywhere between the circumvallate papillae of tongue and the epiglottis. It occurs due to embryonic failure of normal thyroid tissue to descend from base of tongue to neck. Case report: A 16 year old female presented with dysphagia and a mass was seen at base of tongue. Ultrasound showed absence of normal thyroid gland in neck. Fine needle aspiration cytology of mass showed thyroid follicles with colloidal changes, thus, confirming the diagnosis of ectopic thyroid (lingual). Conclusion: Lingual thyroid is rare developmental anomaly and must be kept as differential in tongue masses cases. Surgical excision is treatment of choice.
