The benign osteoblastoma is uncommon, solitary, benign, vascular, bone and osteoid-producing tumor and is the term used by Jaffe and Lichtenstein in 1956.We have experienced a case of this tumor involved in the fifth cervical vertebra.The patient, 28-year old female, was first seen on April 18, 1968. The chief complain was dull pain in her neck and shoulder. The roentgenolgic pictue showed distinct expansion of the right superior articular process. After her admission, the lesion was partly curetted and followed by irradiation of 60Co.The histologic finding consists of an osteoblastic connective tissue stroma which is highly vascular. Within this cellular and vascular tissue, osteoid and primitive bone is deposited.She was last seen on October 10, 1972 at which time there was no evidence of recurrence and was in good health.
