Pleomorphic Adenoma
Comments:
Pleomorphic adenomas (PA) in parotid gland usually involve the superficial lobe (almost 75% of cases), sparing the facial nerve. Facial nerve paralysis should raise the suspicion for malignant transformation. The tail of parotid is the most common site of occurrence. Bilateral and multiple tumors are not common. The image depicts a classic gross appearance of PA with tan white glistening uniform cut surface. The consistency and the gross appearance depend upon the degree of cellularity and the amount and type of stroma. PA arising in the parotid and submandibular gland usually have translucent foci of cartilaginous differentiation.
