Agressive osteoblastoma in a seven-year-old girl’s mandible: Treatment and six-year monitoring

INTRODUCTION: Osteoblastoma is a rare benign bone tumor with locally aggressive behavior in some cases; however, with rare malignant transformations. A case of osteoblastoma in a seven-year-old patient’s mandible is presented. PRESENTATION OF CASE: After the diagnosis, the patient underwent two stages of treatment. In the first intervention, an intralesional curettage was performed as well as a marsupialization of the lesion, in order to reduce its volume and allow a second and more conservative surgical period. In the second surgery, after reducing the lesion, enucleation and rigid internal fixation of the mandible were performed. DISCUSSION: The treatment has proven to be satisfactory, without recurrence of the injury for two years, when the patient suffered a car accident that caused the synthetic material to fracture. Conclusion: The internal fixation was surgically replaced and the patient is being monitored after six years of the initial intervention, without presenting further changes.
