This paper describes a very rare case of basal cell adenoma in the bilateral parotid glands. The patient was a 65-year-old woman with a painless mass in the left parotid gland since she was approximately 20 years old, but she had not sought treatment. Recently, she had also noticed a painless mass in the right parotid gland, and underwent bilateral partial superficial parotidectomies. Histological examination revealed tubular and trabecular type basal cell adenoma of the bilateral tumors. Bilateral parotid gland tumors are rare. Among them, Warthin's tumor is the most common, it is extremely rare for basal cell adenoma to occur in the bilateral parotid glands.
