[Follicular adenoma in lingual thyroid: report of a case]. / Adenoma folicular en tiroides lingual: a propósito de un caso.

We present a case of follicular adenoma which has its origin in a unique lingual thyroid. The interest lies in the oddity of this pathology and in the unusual clinical form of dysphagia. In spite of the fact that the thyroid ectopy is a congenital anomaly in the development of the thyroid, the history of previous administration of cervical radiotherapy and the diagnosis in an elderly person makes us suppose, in this case, that there is a different etiopathology.
