The Glandular Odontogenic Cyst (GOC) was first coined by Gardner et al. [2], in 1988 as an odontogenic origin, is a rare developmental lesion considered a distinct entity because of its uncommon clinical and histopathological characteristics. This lesion can involve either jaws, but the anterior region of the mandible is the most affected area. It strikes distinct age groups, with an average patient age of 50 years. Radiographically, GOC does not display specific or pathognomonic features. It may present as a multilocular or unilocular radiolucencies. The cyst has an aggressive nature and high tendency of recurrence, so long-term follow-up should be carried out. The treatment is controversial, varying from conservative methods to block excision. It is believed that the low prevalence of GOC in the literature is because of not only its rarity, but principally to the fact that its main characteristics are also found in other pathological entities, thereby generating controversial diagnoses. The aim of this paper is to present a rare case of Glandular Odontogenic Cyst (GOC), which is uncommon in the posterior maxilla, that mimicks the lateral odontogenic cyst/botroid odontogenic cyst/Central Muco-epidermoid carcinoma. Owing to its tendency to recur, the lesion needs careful and meticulous planning for its surgical removal.
