Treatment of traumatic bone cyst in a young patient: case report

Abstract

Introduction: Simple bone cyst is an uncommon lesion that can be diagnosed incidentally in routine dental treatment. The most accepted etiopathogenesis suggests that an intraosseous hematoma caused by trauma occurs. It is a non-neoplastic bone lesion, affecting the mandible, with predominance in the posterior region. Objective: To report a case of simple bone cyst in a young patient. Case report: Male patient, 15 years old, was referred to the Buccomaxillofacial Surgery and Traumatology Center after viewing a radiolucent image, being detected in a routine radiographic examination. The patient did not report any complaints and, on physical examination, no alterations were observed, such as an increase in volume or a change in the color of the mucosa. Tomographic examination was requested, which revealed a hypodense, well-defined, bilobular image involving the right mandibular body, extending from tooth 44 to 46. The procedure of choice was incisional biopsy, where the removed material was sent to histopathology, confirming the diagnosis of cyst simple bone. Conclusion: To obtain the definitive diagnosis, a thorough analysis of the clinical, radiographic and surgical findings are essential, as there are other lesions with similar characteristics, making the diagnosis more complex.
