title: 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.
