A Rare Case of Lumbar Chondroma and Review of Literature in This Topic

Enchondroma is a kind of bone hamartoma and a benign hyaline cartilage tumor. Although it is the most common benign tumor of bone, it is quite rare in the spine, especially the lumbar spine. We report a case of chondroma that was located in the lumbar spine, which extended from L2 to L5 in a 4.5yearold child. He visited our clinic with a complaint of spine deformity and limping for 3 years. Surgical resection of large ossified mass was performed and pathologically confirmed to be a benign hamartoma of hyaline cartilage with enchondral ossification. Resection of mass released the tethering effect and balanced the growth speed of spine bilaterally. It is suggestive of a congenital developmental malformation with hamartomatous features and reactive changes.
