Histologic examination of the surgical specimen revealed a well-circumscribed submucosal nodule composed of a central area of hyaline cartilage surrounded by dense, fibrous connective tissue. The patient's postoperative course was uneventful, and there were no signs of recurrence 6 months later.
The term choristoma applies to a cohesive tumorlike mass consisting of normal cells in an abnormal location. Only a few cases of tumorlike masses composed of differentiated cartilage have been reported in the soft tissue of the oral cavity.1 The majority of case reports are found in the dental or oral surgery literature.
