A 6½-year-old boy had a benign osteoblastic lesion in the neck of the right scapula. The differential diagnosis of lytic scapular tumors in children rarely includes benign osteoblastoma and osteoid osteoma. A clear distinction cannot always be made between a large osteoid osteoma and a benign osteoblastoma. The presence of a sclerotic rim on roentgenographic examination of this patient favors the diagnosis of an osteoid osteoma while a size of more than 1 cm suggests a benign osteoblastoma. We emphasize that benign osteoblastoma and osteoid osteoma should be considered as part of the differential diagnosis of lytic scapular tumors in children.
