[Foreign body of the thyroid gland].

A rare case of thyroid foreign body is presented. The swallowed fish bone perforated the pharyngeal wall and migrated to the thyroid gland. The rarity of pathology caused diagnostic difficulties. Despite the correct diagnosis, wait-and-see tactics was initially chosen that delayed surgery and contributed to tissue inflammation. The stages of therapeutic and diagnostic process are analyzed. Endoscopy is not always effective, especially when foreign body migrates from pharyngeal lumen into soft tissues. Ultrasound and CT are necessary for topical diagnosis of migrated foreign body. These methods revealed fish bone migration towards cervical vascular bundle and local complications. Literature data and own experience are analyzed. Early surgical treatment guarantees good results and rapid rehabilitation.
