The region of the jaw may be the site, not only of those peculiar tumors which are associated with the formation of the teeth, but also of most of the tumors which occur in other parts of the body. Of the latter group, the fibroma is probably the most frequent. In rare instances it has been observed to be associated with ossification and has been termed an osteofibroma. As a review of the literature has revealed only fourteen of these cases, it may be of value to point out some of the characteristics in connection with three cases which have come under my observation.
REPORT OF CASES
—M. D., an Italian girl, aged 12, entered the Children's Memorial Hospital on April 2, 1925, complaining of a lump on the right side of her jaw. The swelling had first been noticed about a year before and had grown steadily.
