Squamous cell carcinoma arising in benign adenolymphoma (Warthin's tumor) of the parotid gland

Abstract
Adenolymphoma of the parotid gland is a benign tumor occurring primarily in middle‐aged males. Major texts of surgery and pathology state that this tumor is not malignant nor does it undergo malignant degeneration. This report demonstrates squamous cell carcinoma arising in a parotid adenolymphoma in a patient with no other malignancy or previous irradiation to the head and neck.
