Giant pleomorphic adenoma of the parotid gland.

Pleomorphic adenomas are the most common benign tumors of the salivary glands. These adenomas generally present without pain and are slowly enlarged. However, they can reach enormous sizes, because they are often neglected by the patient and due to late diagnosis and intervention because of fear of surgery or sociocultural factors. This may lead to functional, aesthetic and social problems. In this article, we present a 55-year-old female patient with a giant pleomorphic adenoma in size of 15x15x20 cm, who presented with the complaint of a mass enlarged and swollen for 20 years in her left neck and face and underwent a successful surgery.
