Figure 11 Synchronous second primary malignancy in the lung. A T4a supraglottic squamous cell carcinoma (red arrows) with extralaryngeal invasion is well demonstrated on computed tomography (CT) (A) and positron emission tomography/CT (B). There is a 3-cm hypermetabolic second primary squamous cell carcinoma (yellow arrow) in the right lung apex, discovered at the same time in this patient who had an extensive smoking and drinking history. The rest of the exam is unremarkable.
