Intraosseous hemangioma of the jaws is a rare disease as compared to other skeletal and soft tissue hemangiomas. Preoperative differential diagnosis is critical in that severe bleeding can cause both intra and postoperative complications. Surgical excision of the intraosseous hemangioma can be performed with the use of steroid injection or sclerosing agent into the lesion before the surgical approach. However, even with the embolization of the blood vessels before surgical excision, there still exists a risk of massive hemorrhage during the procedure for the larger lesions. In this report, we present a case of which first tentatively diagnosed as ameloblastoma thus the use of sclerosing agents or vascular embolization was not considered before the surgery. Although there was a strong tendency to intraoperative bleeding, delicate hemostasis was achieved with surgicel(Ethicon SARL, Johnson and Johnson, Switzerland), bosmin(Jeil Pharm, Republic of Korea), and electrocautery. The final histopathological examination confirmed an intraosseous hemangioma of the mandible. The patient is undertaken for follow-up period of 1 year and the prognosis is under favorable condition.
