A 31-year-old man presented with a 6-month history of progressive dyspnea. He also complained of a sensation of a lump in his throat and a voice change. He was otherwise healthy. Flexible laryngoscopy revealed a large, submucosal mass at the base of the tongue that was compressing the epiglottis posteriorly and obstructing nearly 90% of the supraglottis (Figure 1). There was no palpable cervical lymphadenopathy. A computed tomogram (CT) of the head and neck showed a 3.5 × 3.0-cm, nonenhancing, globular, well-defined lesion located at the base of the tongue (Figure 2) and a normal position of the thyroid gland. The results of laboratory studies were within normal limits.
