Extraosseous calcifying odontogenic cyst: report of case and review of literature

Extraosseous calcifying odontogenic cyst: a case report and a literature review

“…They generally appear as circumscribed elevated masses, with smooth surface and firm or soft consistency. Since they have no characteristic clinical appearance they can resemble granulomas, fibrous hyperplasic or fibromas (12,18,19) .…”

“…Review of the epidemiological characteristics of the ECOC has shown that the tumor has predilection neither for gender (6) nor for age (13,15,20) . However, some authors have described two peaks of occurrence in the second and sixth decades (2,12) . Also, no overall predilection was shown for either maxilla or mandible (12) , although a tendency to occur in the anterior region is described (2) .…”

“…As an extraosseous lesion, COC exhibits no or minimal radiographic changes (12) . It may appear as a radiolucent area with scattered amounts of opacities and no relationship with the subjacent bone.…”

“…Despite its variable clinical characteristics, COC is often referred as an asymptomatic slow growing swelling of the jaws or gingival tissues, depending upon whether the lesion is intra-or extraosseous. The extraosseous COC is less common, comprising 12% to 20% of the reported cases (2,12) . Clinically it appears as a localized or pedunculated gingival mass with no distinctive features (2,12) , and radiographically it shows no or only superficial bone involvement with surface erosion (21) .…”
