GLANDULAR ODONTOGENIC CYST IN THE POSTERIOR REGION OF THE MANDIBLE TREATED WITH RESECTION AND BONE GRAFT: A CASE REPORT

Abstract

The glandular odontogenic cyst (GOC) is a cyst of unusual development, with glandular differentiation and potential for recurrence. This report proposes the description of a clinical case of GOC in the posterior region of the mandible exhibiting slight asymmetry to the extra-oral physical examination, multilocular radiographic appearance, expansion of the cortical bone, and reabsorption of involved teeth. An incisional biopsy and anatomopathologic examination were performed. Seven criteria for diagnosis of GOC according to the World Health Organization (2017) were found, and 4 criteria were indicative of aggression and recurrence. In view of the aggressive behavior of these lesions, the indicated treatment was mandibular resection associated with bone graft of the iliac crest. Currently, the patient is being followed up with no signs of relapse for 2 years. It is concluded that clinical, microscopic, and radiographic parameters are useful tools in the prognosis of GOC and should be evaluated in the therapeutic choice to avoid relapses.
