What is sialadenitis most commonly due to?

an obstructing stone (sialolithiasis) leading to Staphylococcus aureus infection; usually unilateral

33

What is pleomorphic adenoma?

Benign tumor composed of stromal (e.g., cartilage) and epithelial tissue;

34

What is the most common tumor of the salivary gland?

Pleomorphic adenoma

What does pleomorphic adenoma present as?

a mobile, painless, circumscribed mass at the angle of the jaw

37

What is the rate of recurrence in pleomorphic adenoma?

High rate of recurrence;

38

In pleomorphic adenoma what often leads to incomplete resection?

extension of small islands of tumor through tumor capsule

39

What does pleomorphic adenoma present as?

Rarely may transform into carcinoma, which presents with signs of facial nerve damage (facial nerve runs through parotid gland)
