A 45-year-old man presents to the ED complaining of focal neck swelling for three days. He claims to have a mildly tender, enlarging mass at the right submandibular area, and claims that it “swells” after he eats. He has mild odynophagia, but denies fever, shortness of breath, drooling, stridor, trismus, globus, and dysphagia.
Here is what you see on visual inspection of his mouth. What is the diagnosis, and how would you treat this condition? See p. 8.
