title: Polytef granuloma clinically simulating carcinoma of the thyroid.
abstract: A case of a foreign body granuloma to polytef (Teflon) appeared as a mass on the left side of the neck and clinically simulated carcinoma of the thyroid. Autopsy results demonstrated that the intracordal polytef extended through the cricothyroid membrane via a fistulous tract forming a suprathyroid nodule.
