Abstract
A case is presented of a euthyroid male in whom a right thyroid mass was discovered. Physical displacement of the right thyroid lobe by a mass determined on CT scan. Scintigraphy and ultrasound showed the mass to be separate from the thyroid. Fine needle aspirations did not predict the tumor. Surgical removal of an adult rhabdomyoma was uneventful. This case and review of the literature demonstrate the rare presentation of a rhabdomyoma as a suspected thyroid nodule.
