Case of Spinal Osteoblastoma in Elderly: Is It Really a Young Patient's Disease?

Background: Osteoblastoma is a benign bone-forming tumor, sometimes locally invasive, that may involve any bone. The highest incidence is between 20 and 30 years of age, and there are no cases described in the elderly. Methods: We report a case of an elderly patient with a lesion in the lumbar spine in which osteoblastoma diagnosis was made. Conclusions: Osteoblastoma is a rare tumor older than 50 years of age, but it should be considered in the differential diagnosis of bone lesions of the spine in adulthood and in the elderly, to avoid a delay in the treatment.
