Simple bone cyst: report of 7 cases

Abstract

Introduction: Simple bone cyst (COS) is defined as an intraosseous cavity of unknown etiology, devoid of epithelial lining and empty or filled with fluid. In the facial region, COS is most commonly seen in the body of the mandible. Objective: The aim of this article is to report a series of COS cases, discussing relevant aspects of the clinical characteristics and adequate treatment. Case report: The case series demonstrated that the presence of asymptomatic radiolucent lesions in the jaws, in which clinical, laboratory and imaging diagnoses were not conclusive, a biopsy is always indicated. Final considerations: In cases of multiple COS lesions, or when they are associated with cemento-osseous dysplasias, a surgical approach is imperative.
