A mixed tumor originating in the palate is rather rare, however, it has been understood that the tumor has a considerable tendency to malignant alteration.
Any surgical intervention to the tumor such as puncture, incision or biopsy could act as a trigger for malignant changes.
Pathologically the malignancy is either adenocarcinoma. squamous cell carcinoma or basal cell carcinoma.
As the mixed tumors are frequently resistive to irradiation the primary treatment should consists of complete surgical removal of the tumor.
The authors described a case in which a surgically removed mixed tumor originating in the soft palate of a 68-year-old male recurred 4 years later.
The recurrence which occurred in the floor of the nasal cavity has been successfully removed by a partial resection of the maxillary bone. The authors discuss the case and have reviewed the related literature.
