title: Chondroblastoma of the lumbar vertebra.
abstract: Chondroblastoma of the vertebra is a very rare condition. To our knowledge fewer than 20 cases have been reported in the world literature. We report a 54-year-old man with chondroblastoma of the fifth lumbar vertebra. The clinical and radiological aspects of the tumor are discussed, emphasizing the presence of an extraosseous mass suggestive of locally aggressive behavior.
