Description

<p>A 46-year-old man who had been diagnosed as having a thyroid mass 15 years earlier was hospitalized to our hospital for severe ulcerative colitis, when neck ultrasonography (US) revealed the thyroid tumor again. Neck US showed the hypoechoic mass with coarse calcification in the right thyroid lobe. A fine needle aspiration cytology showed papillary carcinoma (cT2N0M0). The patient underwent right thyroidectomy and central lymph node dissection. Cut the specimen in half, we found a metallic foreign body inside the thyroid tumor. It looked like an inner needle of core needle biopsy equipment. We confirmed that the patient might have received needle biopsy of the thyroid gland 15 years earlier. It was a very dangerous situation where the needle could have penetrated the adjacent organs such as the trachea and esophagus. Foreign bodies migrating into the thyroid glands are extremely rare. The thyroid has no connection to any other organs and natural course of foreign body migration into the thyroid gland is unthinkable.</p>
