Abstract

A 70-year-old woman was referred to the hospital because of a mass on the right side of the neck. She had a 3-cm smooth, elastic soft mass in the right side of the neck. A CT scan dected a 4×3cm tumor with calcification in the right lobe of the thyroid. A 4×2cm smooth and solid mass was accidently found behind the thyroid tumor at the right side of the trachea during the operation. She underwent a right lobectomy with modified neck lymph node dissection and etipation of the pamatracheal tumor preserving the right recurrent laryngeal nerve. Histological examination revealed follicular carcinoma of the thyroid and concominant paratracheal neurinoma. Her postoperative course has been uneventful without any evidence of recurrence and hoarseness. This case of thyroid cancer with paratracheal neurinoma is very rare. So far only six cases have been reported in this country.
