There have been few case reports of cystic lesions occurring after gingival grafting. There are three reports of this type of sequela after connective tissue grafting, but this is the first known case of a cystlike lesion developing secondarily to a free gingival graft procedure. The bulky tissue, which had developed under the previously grafted area, was properly excised under local anesthesia. The small specimen removed was sent for histologic analysis. A new gingival graft was performed immediately after the lesion enucleation, as the cystic lesion had dislocated the earlier graft. The surgical wound healed uneventfully, and no recurrence was seen 18 months later. The microscopic sections showed a cystic cavity lined with an orthokeratinized, hyperplastic, stratified squamous epithelium covered with fibrous connective tissue. The development of a cystlike lesion following a free gingival graft is, to date, an unpublished event. The fact that most cystic lesions appear in the mandibular lateral incisor–canine–first premolar area deserves further consideration. (Int J Periodontics Restorative Dent 2007; 27:465–469.)
