Salivary duct cysts are acquired cysts that are believed to develop from marked cystic dilation of a salivary gland duct.<BR>The majority occur in the parotid gland, followed by the submandibular gland, and various other salivary glands. Here we report a case of salivary duct cyst of the tongue, together with a review of the literature. A 68-year-old woman was referred to us because of swelling of the tongue.<BR>On examination, a lesion measuring about 30×30mm was found at the front of the tongue.<BR>When palpated, the lesion was soft and slightly tender.<BR>The clinical diagnosis was a cystic lesion.<BR>The cyst was totally extirpated with the patient under general anesthesia.<BR>The histopathological diagnosis was a salivary duct cyst.<BR>This case apparently arose from the anterior lingual gland.
