Normal parotid gland
Benign tumor










 
18 - Parotid gland, pleomorphic adenoma - Gross, cut surface  
Most tumors of this kind present as rounded, well-demarcated, yellow-white masses that rarely exceed a diameter of 6 cm. In some cases, the capsule is not fully developed, and tumor extends to the margin of resection. The recurrence rate with adequate parotidectomy is about 4%, but with attempted enucleation only, recurrence approaches 25%.  
   
Questions:
How frequently does this tumor occur in other salivary glands?
