Abstract
The lateral periodontal cyst (LPC) is an odontogenic lesion that develops along the lateral radicular surface of a tooth. A 59-year-old male patient with a history of liver transplantation due to cirrhosis presented with a radiolucent area with well-defined borders measuring approximately 4 mm in the region corresponding to tooth 13, which was absent. Tooth 12 was endodontically treated and tooth 14 presented pulp vitality. Considering a hypothesis of residual cyst, LPC, or odontogenic keratocyst, and due to the clinical and radiographic aspects of the lesion, an excisional biopsy was performed. Laboratory tests of the patient did not contraindicate the procedure. The anatomopathologic exam showed a cystic capsule aligned by stratified, squamous and nonkeratinized epithelium containing many clear cells, which was compatible with LPC. Therefore, although it is a rare entity, LPC should be included in the differential diagnosis of other lesions that may present with similar characteristics.
