Myxomas of the paraoral--oral soft tissues.

Fifteen cases of soft-tissue myxoma of the paraoral-oral structures have been presented. Eleven cases were garnered from an extensive review of the literature, and four previously unreported cases are described. The myxomas were slow-growing, insidious, infiltrative tumors which occurred in all age groups, with an average patient age of 38 years. Most frequent locations were the cheek, floor of the mouth, and palate. The lesions were present from 2 weeks to 6 years prior to treatment. In this series all the myxomas were treated by surgical excision, with no evidence of recurrences or metastases. The recommended therapy is surgical resection with adequate margins. Other myxomatous lesions which may mimic a myxoma are mentioned.
