Pleomorphic adenoma of the parotid gland with cystic degeneration: A rare case report

Abstract

Pleomorphic adenoma, also called benign mixed tumor, is the most common tumor of the salivary glands. Usually they are found as solitary, unilateral, firm and mobile, painless, slow growing masses. Only 10% of them occur in the minor salivary glands and 90% of them occur in the parotid gland. The incidence of parotid tumor is about 2.4 in 100000/year of all neoplasia of head and neck region, the right side being commonly involved and seen more often in males. Management involves surgical resection by superficial or total parotidectomy.
