SIMPLE BONE CYST: TREATMENT AND FOLLOW-UP OF 24 MONTHS

Simple bone cyst (SBC) is a common benign osseous lesion comprised of an empty or semi-empty cavity within the bone of unknown etiology. A 15-year-old white male patient was referred to an oral diagnostic service for evaluation of a mandibular asymptomatic lesion. The previous medical history was unremarkable. Clinical examination didn't show facial swelling or an expansile buccal surface of the mandible. The mucosa showed no abnormalities. Panoramic radiography revealed a well-defined, unilocular, radiolucent lesion measuring 20 × 20 mm and extending from tooth 43 to tooth 45. There was no root resorption or tooth displacement. Fine-needle aspiration was negative for liquid. Curettage was performed under local anesthesia and the tissue specimen reveled vascularized connective tissue with hemorrhagic areas. The final diagnosis was SBC. The patient remains under 24 months of observation and presents no signs of recurrence. Support: FAPEMIG
