• A case of osteoblastoma in a seven-year-old patient’s mandible is presented.
• Marsupialization of the lesion reduced its volume and allowed a more conservative surgical procedure.
• Patient is in a good general state with no recurrence after six years.

IntroductionOsteoblastoma 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 caseAfter 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.DiscussionThe 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.
