Adenoid cystic carcinoma on the dorsum of the tongue.

Adenoid cystic carcinoma is a relatively rare epithelial tumor of the salivary glands accounting for about 5-10% of all salivary gland neoplasms. Approximately, 31% of salivary gland neoplasms affect minor salivary glands particularly the palate. It involves tongue in only 19.8% of cases and even rarely the dorsum of the tongue. We report such a rare case that affected dorsum of the tongue in a 45-year-old-female patient.
