RESUMO
Burkitt lymphoma (BL) is a rare and aggressive malignant neoplasm frequently involving the jawbones in children. The main purpose of this article is to report the case of a nine-year-old boy with widespread BL diagnosed through oral findings. The patient was referred after complaining of dental mobility for two weeks. The physical examination revealed premature eruption of permanent teeth. The periapical radiographic examination showed a diffuse bone rarefaction in the involved area. An incisional biopsy was performed, leading to the diagnosis of BL. The patient was then treated with chemotherapy and is free of disease after an 18-month follow-up. The main signs and symptoms of an oral BL could mimic a dental problem, thus it is extremely important to be knowledgeable about this disease, which can be fatal without early diagnosis and treatment.
