A month after the patient had noticed the unfitted denture, the pedunculated tumor mass, lobulated and measured about 3 cm in diameter, arose from the reconstructed skin portion of the floor of the mouth.<BR>The mass was resected but recurred three weeks later, so that re-resection and wide elimination of denture were carried out.
