Glandular odontogenic cyst mimicking a radicular cyst: A case series

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.
