Case Summary and Diagnostic Information

This is a 28-year-old white male who presented with a bony bump above teeth #s 10 and 11.  This lesion was first noticed by his general dentist in September 2004 and later by the oral surgeon on 10/30/2005.  It was expansile, especially labially.  The bone supporting the two teeth was compromised, but the teeth were not mobile.  The area was biopsied on 11/02/2005.  The area was described as a solid mass with a gelatinous consistency.  It was 2 x 1.5 cm in size.  The lesion did not perforate into the maxillary sinus or the nasal cavity. The roots of teeth #s 10 and 11 were devoid of bone on the interproximal surfaces and a significant amount of the labial cortex was missing.  The patient is on follow-up in 3-month intervals.
