<prompt> A 40-year-old woman presents with a painless mass anterior to her left ear. The mass had been slowly enlarging over the past year. The mass is firm and nontender. Computed tomography and magnetic resonance imaging reveal a well-circumscribed, homogeneous mass within the left parotid gland. Biopsy reveals anastomosing strands of stellate and fusiform epithelial cells embedded in a myxoid stroma. Which of the following is a characteristic of the lesion?It is also called papillary cystadenoma lymphomatosum.It is most often localized to the submandibular glandIt is the most common malignant salivary gland tumor.Recurrence often takes place after surgical resection  <response>: Pleomorphic adenoma Mixed tumor. - Approximately 80 to 90 of salivary gland tumors originate in parotid gland of these, approximately 70 are pleomorphic adenomas. - The term mixed tumor properly applies to this benign tumor, which often demonstrates myxoid cailage-like elements in addition to stellate or fusiform epithelial cells. - Complete surgical resection is difficult because of tumors proximity to facial nerve - thus, recurrence is frequent
