XXXX of the oral cavity: review of 10 cases.

@entity1 @entity66 @entity548 @entity5 @entity2117 @entity158 @entity320
Oral @entity320 is uncommon, comprising less than 1% of all @entity320 . Consequently, few cases have been reported from any one institution. We report 10 cases of @entity320 seen at the Mayo Clinic between 1905 and 1979. The site of the @entity5 was the hard palate in 4 @entity1 , the soft palate in 2 @entity1 , the lower alveolus in 2 @entity1 , and the upper alveolus and the retromolar trigone in 1 @entity1 each. Eight of these @entity5 occurred in @entity1 , and 8 @entity1 were older than 60 years of age. Presenting symptoms were a pigmented mass in 9 @entity1 , @entity158 in 5 @entity1 , and @entity548 in 3 @entity1 . In 4 @entity1 , the @entity5 occurred in an area of preexisting @entity2117 . The treatment of choice in this disease is surgery; it is the only form of therapy with curative potential. Radiation therapy produced @entity5 regression in one @entity1 in whom the @entity5 was considered inoperable, although there was no effect on eventual survival. Chemotherapy was ineffective in producing @entity5 regression. The prognosis of @entity1 who have @entity320 is dismal; the median survival time in this series was 16 months after diagnosis. Early diagnosis of @entity66 in the mouth and adequate @entity5 resection may improve the prognosis in this disease; however, once the @entity5 recurs, there is essentially no possibility of prolonged survival.
