Dual Ectopic Thyroid: A Case Report and Review of the Literature

Alina Fernández-Genao et al. J Brown Hosp Med. .

Abstract

Ectopic thyroid tissue is an uncommon anomaly, and the presence of dual ectopic thyroid tissues in a single patient is exceedingly rare. We describe a 69-year-old woman who presented with dyspeptic symptoms, asthenia, aphonia, and chronic fatigue. The patient was eventually found to have a multinodular goiter, cervical goiter, and mediastinal goiter. The patient underwent radical thyroidectomy and dissection, followed by treatment with levothyroxine. This report underscores the diagnostic challenges in complex presentations of ectopic thyroid tissue.

Keywords: ectopic thyroid; endocrinology; thyroid diseases; thyroid dysgenesis; thyroid gland.

Thyroid tissue in which follicular structures of variable size are appreciated, some conglomerate, others dilated, with eosinophilic content of colloid appearance, lined by cubic cells without atypia. In some areas, there is fibrous and colloid degeneration.
