A 82-year-old man presented with a rapidly growing mass on the left upper cheek for approximately three weeks. The mass measured 3 × 3 cm and was freely movable. The dentist removed it from the posterior buccal mucosa (Fig. 47.1) with a preliminary diagnosis of mixed salivary gland tumor. The patient denied chills and fever, but he claimed to have 12-pound weight loss in four months. A bone marrow biopsy was subsequently performed (Figs. 47.2 and 47.3).
