Case 2 Conclusion


	With no periapical radiolucencies noted, no pain on percussion of the teeth, and the swelling located just buccal to the edentulous span, the top of any differential diagnosis should include residual cyst. As such, a reasonable and cautious initial step is to aspirate the lesion.


	*On aspiration of Mrs. Evans lesion, ½cc of straw colored fluid was obtained, consistent with a residual cyst and allowing exclusion of a hard tumor or a potentially hazardous vascular lesion.*


	As such, Mrs. Evans was consented and a full-thickness mucoperiosteal flap was made and bluntly dissected and reflected superiorly. The lesion was visualized, enucleated, and the site was curetted until all bony walls were apparent.


	*No tooth roots were exposed. The surgical site was irrigated, suctioned dry, and closed with interrupted 3-0 silk sutures.*


	*There were no surgical complications. The lesion was placed in 10% buffered formalin, labeled, and submitted to the oral pathologist for histopathologic evaluation.*


	Histopathological evaluation revealed a hyperplastic stratified squamous cystic lining covering well-vascularized connective tissue. Both the epithelium and connective tissue showed evidence of inflammatory infiltrate consisting primarily of polymorphonuclear leukocytes and lymphocytes.
