Glandular odontogenic cyst mimicking a radicular cyst: A case series

Abstract

Glandular odontogenic cyst (GOC) is considered an odontogenic cyst of developmental origin, which because of its histological features had been termed sialo-odontogenic cyst. Although clinically and radiologically they bear similarity to relatively innocuous periapical lesions, their biological behavior is comparable to aggressive tumor-like conditions-like keratocystic odontogenic tumors. Their aggressive nature, ability to attain large dimensions, and relatively high recurrence potential entail that they should be viewed as diff erent propositions from the treatment perspective. Due to the rarity of these lesions, there are no well-established surgical treatment protocols so far. Nevertheless, cases histologically confi rmed as GOCs warrant critical review and extended follow-up. This paper presents two reports of glandular odontogenic cysts which involved the posterior maxilla and their treatment outcomes.

Glandular odontogenic cyst—Report of a rare case

“…Due to its tendency to recur after conservative surgical approach, some authors prefer marginal resection and segmental resection especially in larger lesions. The high rate of recurrence can be attributed to thin lining, multilocularity of cyst, presence of microcysts, and high mitotic capacity of cells similar to odontogenic keratocyst . Some authors have also reported that larger lesions that have perforated the cortical bone and are radiographically multilocular have more chances to recur.…”

These lesions would be amenable to radical approach such as marginal or segmental resection with or without resection of overlying mucosa.…”
