Mandibular exostosis following an epithelial–conjunctival graft: a case report

Observation: A 68-year-old patient presented to us because of the gradual onset of symptoms associated with a mass located on an epithelial–mucosal graft performed approximately 20 years ago. A provisional diagnosis of exostosis was made and the mass was excised under local anesthesia. Comments: Exostosis is defined as a localized benign bone proliferation constituting a sessile nodular bony outgrowth with either a broad base or a peduncle attaching to the parent bone. Some cases of exostosis secondary to the realization of gingival grafts have been reported in the literature. Thus, exostosis should be considered as an unpredictable side effect of this surgical procedure
