Purpose: The oral teratoma is found approximately in live birth at the rate from 1 : 35,000 to 1 : 200,000. In a review of literature 16 cases of midline teratoma with cleft palate were reported. We report a case of congenital palatal teratoma with cleft palate in a 1-year-old girl. Methods: A 1-year-old girl was admitted our institution for the closure of cleft palate. On the intraoperative findings there was $4{\times}1{\times}0.5cm$ sized hairy soft mass at the midline and complete cleft palate. We did incisional biopsy intraoperatively and its pathology revealed heterotopic brain tissue. The excision of remaining mass and palatoplasty with Sommerlad's method were performed. The final pathology of the mass was mature cystic teratoma. Results: After the operation there were neither recurrence nor oronasal regurgitation. Conclusion: We report for one patient with congenital palatal teratoma associated with cleft palate and obtained an excellent result.

Epignathus is a rare congenital orofacial teratoma that arises from the sphenoid region of the palate or the pharynx. It occurs in approximately 1:35,000 to 1:200,000 live births representing 2% to 9% of all teratomas. We present the case of a newborn of 39.4 weeks of gestation with a tumor that occupied the entire oral cavity. The patient was delivered by cesarean section. Oral resection was managed by pediatric surgery. Plastic surgery used virtual 3-dimensional models to establish the extension, and depth of the tumor. Bloc resection and reconstruction of the epignathus were performed. The mass was diagnosed as a mature teratoma associated with cleft lip and palate, nasoethmoidal meningocele that conditions hypertelorism, and a pseudomacrostoma. Tridimensional technology was applied to plan the surgical intervention. It contributed to a better understanding of the relationships between the tumor and the adjacent structures. This optimized the surgical approach and outcome.

The soft tissue tumors that occur commonly in newborn infants include palatal and gingival cyst of the newborn, congenital epulis, hemangioma, teratoma, pyogenic granuloma, and irritation fibroma. Such soft tissue tumors in the alveolar ridge of newborns are usually treated by surgical excision. If untreated, they can cause airway obstruction and breathing difficulty due to aspiration. They also cause discomfort during oral feeding. If nasal feeding is tried, since vomitting is impossible, there is a risk of aspiration pneumonia. In this case, a newborn infant visited our hospital with soft tissue tumor as chief complaint, and the infant was treated by surgical excision. It appeared to be similar to pyogenic granuloma and irritation fibroma upon histologic exam. However, it was different from those diseases since multinucleated giant cells were observed and it was congenital. The pathologic process of this neoplasm is not clear. This case is reported, since it is difficult to classify it as a specific disease.
