Squamous metaplasia in a multinodular goiter: a case report.

ABSTRACT

Squamous epithelium in thyroid is an unusual finding. It is seen in a variety of inflammatory and neoplastic conditions. It's presence has been attributed to metaplastic change of follicular epithelium by some authors and to the persistence of ultimobranchial body by others. We encountered a case of multinodular goiter with groups of squamous cells lining a cystic cavity. We report it because of it's rarity with a brief review of literature.
