A 75-year-old man presented with an incidental finding of a lesion in his base of tongue on positron emission tomography (PET). He was asymptomatic and denied dysphagia, weight loss, hoarseness, or shortness of breath. The PET scan had been performed as follow-up after surgical treatment for non–small cell lung carcinoma and renal cell carcinoma in 2004 and 1989, respectively. He had been a smoker in the past and consumed 6 alcoholic drinks per day. Fiberoptic examination revealed a 3 × 3-cm, soft, smooth-surfaced, submucosal mass arising from the right lateral oropharyngeal wall adjacent to the base of tongue.
