SIMPLE BONE CYST - CLINICAL CASE REPORT

Abstract

The World Health Organization classifies simple bone cyst as a non-neoplastic lesion related to bones, defined as an intraosseous cyst, which features a thin capsule. Its etiology remains unknown, and the most accepted explanation is related to the history of trauma. It is in most cases clinically asymptomatic and the diagnosis is often established through routine radiographic examination. The objective of this study is to report a case of a simple bone cyst in the left mandible region in a young patient underwent imaging  examinations for follow-up orthodontic treatment.The patient attended the Maxillofacial Traumatology Surgery Service showing circumscribed unilocular radiolucent lesion, in the left mandible region.Reported no significant swelling or pain symptoms. Excisional biopsy was performed and histopathological findings showed bone tissue associated with a thin membrane of connective tissue, and absence of epithelial lining. Today, after two years of surgical treatment, there is no evidence of recurrence.
