Are All Head and Neck Squamous Cell Carcinomas Created Equal?

The patient was a 70-year-old man with a 6-month history of a progressively enlarging right neck mass. His medical history was significant for numerous basal cell carcinomas and chronic lymphocytic leukemia. He was a never-smoker and a social drinker. On examination, the mass was in level II, fixed, and nontender. Examination of the oral cavity and mucosal surfaces of the pharyngeal axis by endoscopy showed normal results. Computed tomography (CT) of the neck demonstrated a 2.4 × 2.5 × 2.0–cm cystic lesion in the right upper neck with infiltration of the sternocleidomastoid (Fig. 1).
