[Telangiectatic osteosarcoma of the scapula: a case report]

Telangiectatic osteosarcoma is a rare entity and rarely involves flat bones. The authors report the case of a 4 year old child, with a four month history of progressive left shoulder swelling. Radiographs and CT of the left shoulder revealed a large lytic lesion with cystic areas of the scapula, simulating the appearance of an aneurysmal bone cyst. Surgical biopsy was performed and showed telangiectatic osteosarcoma.
