Treatment

Under local anesthesia, an incisional biopsy was performed. The procedure involved laying a buccal flap in the area of teeth #s 18-21. Upon laying a flap, perforation of the buccal cortex was noted and the inferior alveolar nerve had been pushed buccally making it difficult to aggressively remove the mass. Small tissue samples were removed and submitted for microscopic evaluation. There was very little bleeding. Post operatively, the patient did well but has mild parasthesia of the lower lip and chin believed to be due to the nerve being pushed buccally. The patient is currently kept on recall visits to closely monitor any changes.

Incisional Biopsy

This biopsy was read by Dr. Thomas Morton, Oral Pathology Biopsy Service, School of Dentistry, University of Washington. Histologic examination reveals multiple pieces of soft tissue composed of loose and myxoid connective tissue containing a lesion of vascular origin. The latter is made up of vascular spaces of variable shapes and sizes lined by one layer of flat endothelial cells and separated by loose connective tissue.
