Abstract

Abstract: A Glandular Odontogenic Cyst (GOC) is a rare developmental cyst of odontogenic origin. Occurrence rate is low, with less than 150 cases reported in the literature thus far.1 GOCs can be misdiagnosed due to clinicopathological similarities to other odontogenic cysts, including those of a benign and malignant nature. A wide range of ages can be affected, with a mean age of 45.7.2 The most commonly affected site appears to be the anterior mandible. An unusual presentation of a GOC affecting the right posterior mandible of a 42-year-old male is reported.

CPD/Clinical Relevance: This article highlights the importance of appropriate special investigations for a glandular odontogenic keratocyst and treatment modalities.

Article

A glandular odontogenic cyst (GOC) was first introduced as a distinct clinicopathologic entity by Gardener et al in 1988 with the World Health Organization subsequently acknowledging this in 1992. The most common presentation of GOC is a unilocular radiographic lesion2 affecting the anterior mandible of middle-aged individuals with a slight male predilection.3

Presentation in the maxilla is much less common at 30%, compared with 70% of cysts affecting the mandible.2 A GOC can often be misdiagnosed as other cysts of the jaw, including those of a benign or malignant nature,4 due to the non-specific clinical and radiographic features.

Recurrence rates of up to 55% have been reported and occur, on average, 2.9 years following initial treatment.5 Features of GOC which may predispose to higher risk of recurrence are thought to be size, locularity and treatment modality, with higher recurrences seen in large multi-locular cysts treated with enucleation or curettage alone.1 The literature quotes osteotomy or surgical resection as the most suitable option for management of these aggressive cases.6
