Primary tumors involving the bony skeleton of the chest wall are uncommon. After a retrospective review of the histopathology archive at our institution from Oct 08 to Mar 09 we found three malignant neoplasms affecting the rib, clavicle and the costal cartilages, one mesenchymal chondrosarcoma, one case of clear cell chondrosarcoma and an aggressive osteoblastoma each having distinctive histological diagnosis. Our limited experience in the occurrence of primary chest wall tumors showed that there are occurrences of rare bony lesions. A strong clinical suspicion, clinico-radiological correlation and histopathological confirmation are required for proper evaluation.
