Abstract

We present a case of a patient with two lateral periodontal cysts in the maxilla and the mandible, respectively, and review the English literature on multiple lateral periodontal (LPCs) cysts and/or gingival cysts (GCs) and botryoid odontogenic cysts (BOCs). The patient was a 59 year-old female with two fluctuant swellings covered by semi-lucent mucosa on the attached gingiva between the maxillary and mandibular right canine and first premolar teeth, respectively. Periapical radiographs revealed at the respective sites between the roots of the canine and first premolar teeth areas unilocular radiolucencies. Intra-operatively, the presence of bone cavities was confirmed at both sites. The microscopic features were consistent with LPC. The review of the English literature on multiple LPCs and/or GCs and BOCs found seven reports of multiple LPCs, four of multiple GCs, and two with an LPCs and a GC. It is concluded that multiple LPCs have been rarely reported in the literature, but should be included in the differential diagnosis of multifocal radiolucencies lateral to vital teeth. The possibility of multiple lesions in different locations should direct to a thorough clinical and radiographic examination in a patient diagnosed with an LPC or GC. Key words:Jaw cysts odontogenic cyst, lateral periodontal cyst, multifocal unilocular radiolucencies.

Highlights

Lateral periodontal cyst (LPC) is a developmental odontogenic lesion that usually occurs in the anterior-premolar area of the mandible, lateral to the roots of vital teeth (1)
We present a case of a patient with two LPCs, one in the maxilla and one in the mandible, respectively, and review the English literature on multiple LPCs and/or gingival cyst (GC)/botryoid odontogenic cysts (BOCs)
The cysts presented could be LPCs perforating the cortical bone of the jaws and extending beneath the oral mucosa, or GCs causing bone erosion

Summary

Introduction

Introduction Lateral periodontal cyst (LPC) is a developmental odontogenic lesion that usually occurs in the anterior-premolar area of the mandible, lateral to the roots of vital teeth (1). We present a case of a patient with two LPCs, one in the maxilla and one in the mandible, respectively, and review the English literature on multiple LPCs and/or GCs/BOCs. Case Report A 59 year-old female was referred for diagnosis and management of two gingival swellings discovered during routine dental examination.
