Chondroblastic Osteosarcoma with Multiple Organ Metastasis Including to the Pancreas Metastasis. Case Report

　骨原発性悪性腫瘍，特に骨肉腫では遠隔転移の好発部位は主に肺，骨などがあげられる．しかしながら膵臓転移の報告は稀である．今回，37歳の男性の右第2肋骨に発生した軟骨形成性骨肉腫の症例で，肺転移など多発性転移を来した後に，膵臓転移がみられた症例を報告する．

　It is wellknown that lung and bone are common sites of metastasis by primary malignant bone tumos, and that the pancreas is an extremely uncommon site. We report a case of chondroblastic osteosarcoma arising from the right second rib in a 37-year-old male in which CT examination revealed metastasis to the pancreas after metastasis to other sites, including the lung.
