This case is presented because, first, it illustrates one of the unusual conditions that occur about the mouth and, secondly, it brings out the possibilities of uncommon diagnoses of rare pathologic conditions about the jaws—conditions that arouse the interest of the oral surgeon.
REPORT OF CASE
A school girl, aged 15, with a large swelling under the tongue, stated that during a physical examination, three weeks before, attention was directed to this swelling, but that prior to this time she had not noticed anything unusual or abnormal existing in her mouth. She had not had pain or discomfort. Within the past two weeks she had noticed a rapid growth of the swelling, and for the first time she was beginning to have difficulty with speech and mastication. There was nothing in the past medical history that had any bearing on the present condition. The family history was negative.
