Small cell osteosarcoma of rib: diagnosis and treatment of the rare case.

ABSTRACT

Small cell osteosarcomas are very rare tumors which are classified as the component of Ewing's sarcoma family. Although the tumor generally is seen on long bones, short bone involvement is rare. Moreover, rib localization is quite uncommon and to the best of our knowledge, only one case has been reported so far. Herein, we described a case of rib-localized small cell osteosarcomas which was only presented with localized left sided pain. Resection surgery followed by adjuvant chemotherapy was performed. Clinico-pathological features and therapeutic approach are discussed in the light of the relevant literature.
