Telangiectatic osteosarcoma is a rare variant of osteosarcoma. The rib is an uncommon primary site for conventional osteosarcoma, and even more for telangiectatic osteosarcoma. Because this tumor consists of single to multiple cystic cavities that contain blood or necrotic tumor with no appreciable areas of sclerosis, careful observation is needed to differentiate this malignancy from other benign cystic lesion. Therefore primary differential diagnosis including telangiectatic osteosarcoma is important, although rib is not the predilection site of telangiectatic osteosarcoma. We present a case of telangiectatic osteosarcoma arising in a rib. We reviewed the literature concerning telangiectatic osteosarcomas and primary osteosarcomas arising from the rib. The differential diagnosis of telangiectatic osteosarcoma and clinical features of osteosarcomas arising from unusual locations were discussed.
