Simple bone cysts are pseudocysts affecting long bones and, less frequently, the jaws, especially the mandible. These cysts are generally detected during routine radiography, with the frequent observation of a well-delimited radiolucent area sending projections between the roots of the teeth involved. Simple bone cysts are mainly diagnosed during the second decade of life and have an excellent prognosis, but their etiology is uncertain. The aim of this paper is to report the case of a simple bone cyst in a 15-year-old adolescent seen at the Stomatology Outpatient Clinic, School of Dentistry, Federal University of Bahia. The etiology, clinical course and prognosis of this lesion are discussed based on a systematic review of the literature.
