Introduction: Odontogenic cysts develop within the normal dental follicle that surrounds an<br />
unerupted tooth. These cysts can grow very large and can move teeth, but more commonly are<br />
relatively small. We describe a young male who presented to the ED with the complaint of right<br />
facial swelling of two months that was determined to be a large odontogenic cyst.<br />
Case Description: A 10 year old male with no significant medical history was brought to the<br />
emergency department complaining of right facial swelling for two months significantly<br />
worsening over the preceding two weeks. The swelling began after he was punched in the face<br />
with a soft glove. He had no recent fever, dental pain or recent dental work performed.<br />
The patient was well appearing in no distress. Examination was significant for a large amount of<br />
swelling over his right cheek/mandibular region without discernable borders. The swelling was<br />
non-tender to palpation. The remainder of the exam was non-contributory.<br />
CT of the facial bones demonstrated an expansile septated hypoattenuated mass measuring<br />
9.2x4.7x5.1cm centered about the right mandible and mildly displacing surrounding structures.<br />
This was suspicious for a dentigerous cyst.<br />
Discussion: Odontogenic cyst is a broad term describing a variety of cysts defined as epitheliallined<br />
structures derived from odontogenic epithelium and are further subdivided by location and<br />
histologic characteristics.<br />
Complete history and physical examination along with radiologic examination are the first steps<br />
in the evaluation of jaw related cysts and tumors. Fine needle aspiration, open biopsy or<br />
excisional biopsy may be necessary for definitive diagnosis.<br />
The case presented is significant for the growth rate and large size of the cyst at presentation to<br />
the ED. CT scan is the most appropriate modality for appropriate visualization of the mass. The<br />
follow up provided to the patient is of maximal importance as odontogenic masses can require<br />
extensive treatment.<br />
