Mixed tumor of skin.

A 40-year-old white male consulted his dentist because of a mass in the upper lip to the right of the midline. The patient stated that the lesion had been present and slowly enlarging for at least the pat 10 years. A mass that appeared to be about the size of a hazel nut was apparent to direct visualization and it produced an elevation of the lip surface. On palpation, the mass was found to have a firm rubbery texture and to be freely movable. The history of slow growth of an apparently well delineated mass over a lengthy period of time, together with a lack of fixation to the surrounding tissues of the lip was considered indicative of a benign lesion. The mass was extirpated using an intraoral approach under local anesthesia.
