Primary hemangioma of the bone arises within the bony substance as opposed to hemangioma which arises in other tissue and then invades the bone. The former is rare, but is occasionally found in vertebrae, skull or facial bones, and the latter sometimes occurs in the nasal cavity, nasal septum or sinuses. We treated surgically a 41-year-old female with primary hemangioma of the nasal bone. She complained of swelling of the root of the nose and pain for 3 years. Roentgenograms of the nasal bone revealed radiating bony trabecula, so called "sunray spicula" or "sunburst", particularly in the lateral view. At the time of operation, the tumor found to have invaded the inner and outer tables of the nasal bone and consists of vascular spaces, described as "honeycomb". Postoperative pathological study revealed it to be a cavernous hemangioma. There has been no recurrence of the tumor for 3 years.
