Central giant cell granuloma is a rare giant cell disease. To date, the etiology is not clearly understood, and the main treatment strategy is surgical curettage. Our case report was a 4-year-old boy with the chief complaint of bilateral cheek swelling. He had no underlying symptom and systemic disease. In clinical examination, there were two dense tumors occupied bilateral mandibular from first molar to ascending ramus. The panoramic X-ray film revealed multilocular well-defined radiolucent lesions. According to these findings, clinical diagnosis of cherubism, ameloblastoma, and central giant cell granuloma were suspected. The boy subsequently underwent curettage of the tumors, and the pathologic report was bilateral central giant cell granulomas of mandible. The left side wound was healed well, but right side one recovered slowly, so the boy received another surgery again after 6 years. The wound of the right mandible was healed better and no sign and symptom of recurrence were noted so far.
