Abstract

Warthin's tumor is the second most common benign tumor of the parotid gland. Malignancy arising from Warthin's tumor is extremely rare, and only 29 cases have been reported. Diagnosis can be made prior to the surgery, but in many cases, the disease is detected through postoperative pathology report or by recurrence of the mass lesion. We report a case of polymorphous low grade adenocarcinoma arising from Warthin's tumor diagnosed by the excision of a parotid mass and treated by an additional surgery of superficial parotidectomy. The postoperative pathology report revealed no residual cancer cells and the patient is free of disease for 8 months since the operation.
