Benign cystic teratoma of the parotid salivary gland: report of the first case in Thailand.

An extremely rare case of benign cystic teratoma of the parotid salivary gland is presented with a review of the literature. It was found in a 35-year-old Thai woman farmer who had had a history of a movable mass at the left parotid gland region for about 20 years. The microscopic examination revealed benign cystic teratoma of the parotid salivary gland. There is only one reported case in the literature, so, this is the second reported case.
