Case Report Diagnostic Dilemma: A Case Report of Odontogenic Keratocyst in Lateral Periodontal Position

Odontogenic keratocyst is a common cyst of the oral cavity with high recurrence rate and it has an ability to mimic other jaw cysts. Present study is a case report of a 45 year old woman presenting with an asymptomatic swelling on the gingiva between the mandibular left premolars. On clinical and radiographic examination, a provisional diagnosis of lateral periodontal cyst was given. Histopathological examination revealed odontogenic keratocyst. The lesion was successfully treated by complete enucleation. The aim of the study is to report a case of odontogenic keratocyst simulating lateral periodontal cyst. Emphasis was given to distinguish odontogenic keratocyst from other laterally positioned cysts and its cause for aggressive behavior and high recurrence rate.
