A 35-yeаr-оld previоusly heаlthy mаle patient presented tо the emergency department (ED) of a tertiary care facility with fever, throat pain, and difficulty breathing. The previous history was unremarkable, except for injury after swallowing a fish- bone. One week prior to admission, the patient reported the symptom of a sore throat that improved slightly after 2 days of self-prescribed penicillin. However, a worsening sore throat returned the day prior to admission. In the ED, the patient was found to have a sore throat, odynophagia, poor oral (p.o.) intake, right neck tenderness, and a fever of 40.1°C. The patient also reported a recent development of trismus and muffled “hot potato” voice. Upon an evaluation, the patient was started on dexamethasone and intravenous (i.v.) ampicillin-sulbactam (2,000 mg/kg, once a day [q.d.]). Ibuprofen was also administered for pain management, with mild improvement and a resolution of fever, and the patient was admitted. A CT was performed [image].

A 73-yeаr-оld mаn cоmplаined оf a swelling along the anterior border of the sternocleidomastoid (SCM) in the anterior cervical region (anterior triangle). On examination by his physician, a small, firm swelling was palpated in the submental triangle. It was moveable on the deep tissues and was not attached to the skin. Similar swellings deeper in the neck along the course of the internal jugular vein made the region of the SCM generally swollen. During examination of the man's mouth, a small carcinomatous ulcer was detected on the left side of the apex of the man's tongue. When asked how long this "sore" was on his tongue, the man said it has been there for several months but it was not painful so he ignored it. Which of the following statements best describes the most likely cause of the swellings in the submental and lateral regions of the man's neck?
