Osteosarcoma (OS) is a common primary malignant tumor of bones that produces osteoid matrix. Telangiectatic osteosarcoma (TOS) is a rare variant of OS. It affects the long bones especially the lower end of femur and the upper ends of tibia and humerus, a distribution similar to the conventional osteosarcoma. The rib involvement is very infrequent. We present a case of TOS of the rib that posed a diagnostic difficulty owing to its unusual location and to its resemblance to giant cell tumor and aneurysmal bone cyst. Correspondence.
