The difficulty in recognition of the presence of a slow-growing malignant neoplasm involving the floor of the right nostril in a child aged 5 years prompts the report of this case. At the first observation the lesion had the picture of a furuncle involving the nasal floor.
The adamantinoma is a slow-growing tumor, insidious in onset. The symptoms may be so slight that not until the tumor has advanced can it be recognized clinically. Roentgenograms of the teeth and sinuses are inconclusive. It is a tumor that destroys by invasion and secondary infection. It is resistant to roentgen radiation but does respond to a degree, as this case demonstrates.
The adamantinoma arises from cells concerned with tooth development and is classified under the general heading of epithelial odontomas. It is multilocular and microscopically shows masses of epithelial cells of the enamel organ type of ameloblasts, cuboidal cells and stellate reticulum.
