A 25-year-old woman presented with a 2-month history of a gradual increase in right facial swelling and mild, generalized pain in her right cheek. Physical examination revealed a nontender, soft, freely mobile, 4-cm mass in the region of the right parotid gland, with no overlying erythema or associated cervical adenopathy. A contrast-enhanced computed tomogram revealed diffuse enlargement of the right masseter muscle, with asymmetrical internal enhancement and no involvement of underlying bone. The parotid, submandibular, and sublingual glands appeared normal (Figure 1).
