Ectopic lingual thyroid as unusual cause of progressive Dysphagia
Keywords:
Key words:Dysphagia, Lingual Thyroid, EctopicAbstract
Lingual thyroid gland is a rare clinical entity that is due to abnormal migration of the thyroidtissue during embryonic development. Wepresent a case of lingual thyroid with hemi-agenesis of right lobe and colloid nodule in the left lobe presenting with difficulty in breathing and swallowing with choking episodes. Thorough clinical examination and investigations were carried out. The lingual mass was removed and sent for histopathological examination, which ultimately confirmed the diagnosis of lingual thyroid tissue. We are presenting the case for its rarity in general practice and because of its unusual presentation. Theliterature is reviewed regarding the incidence and diagnosis of lingual thyroid with possible treatment options discussed. The clinicians and the radiologists must be aware of this entity to avoid mistaking itfor evidence of invasion by a malignant neoplasm.
